| In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: f_tcm: fix deadlock in usbg_make_tpg()
usbg_make_tpg() held dep_lock while calling
configfs_depend_item_unlocked(), which acquires the configfs root
inode lock when operating across subsystems. This creates a circular
lock dependency with configfs_rmdir():
dep_lock -> configfs root inode lock -> su_mutex -> dep_lock
In usbg_make_tpg(), dep_lock only serialized the read of opts->ready,
which is a monotonic flag that transitions from false to true exactly
once (in tcm_set_name()) and never reverts. Remove dep_lock from
usbg_make_tpg() entirely and use READ_ONCE/WRITE_ONCE to access
opts->ready locklessly instead. |
| LibRaw 0.22.0 contains an incorrect numeric conversion vulnerability in LibRaw::parse_tiff_ifd() when processing TIFF tag 0x00fe (NewSubfileType). A specially crafted RAW, TIFF, or DNG file can supply an attacker-controlled NewSubfileType value outside the range of a signed int. The parser converts this value and narrows it to int without performing range validation. This out-of-range conversion triggers undefined behavior, resulting in process termination and denial of service. |
| Improper handling of compressed data in the shared GZIP decompressor used for AMQP 0-8/0-9/0-9-1 and AMQP 0-10 message delivery, message conversion and HTTP management JSON rendering allows authenticated message producers to exhaust memory and disrupt broker availability via processing without a decompressed-output limit.
This issue affects Apache Qpid Broker-J: through 10.1.0.
Users are recommended to upgrade to version 10.1.1, which fixes the issue. |
| The GeoDirectory – WP Business Directory Plugin and Classified Listings Directory plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'business_hours' parameter in all versions up to, and including, 2.8.183 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is possible because the AJAX save handler validates only post authorship and a nonce with no additional capability check, allowing any subscriber-level user who owns a listing to exploit this vulnerability. |
| The Zero Spam for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Nested POST Array Keys via Contact Form 7 Integration in all versions up to, and including, 5.7.10 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The payload is delivered by submitting a Contact Form 7 request with a nested POST array key containing arbitrary HTML or JavaScript — PHP parses the field name into a nested array key, which is stored verbatim in the zerospam_log.submission_data column when Zero Spam flags the submission as spam due to the absence of the zerospam_david_walsh_key field. |
| The Repeater Fields for Elementor Forms plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Repeater Field Value in all versions up to, and including, 2.2.7 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. |
| The Premium Packages – Sell Digital Products Securely plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'cart_items[][product_name]' Parameter in all versions up to, and including, 7.2.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The checkout REST route uses permission_callback set to __return_true and the invoice loader performs no order ownership check, meaning an unauthenticated attacker can both persist the payload and ensure it is renderable to any logged-in user who accesses the invoice. |
| The Online Scheduling and Appointment Booking System – Bookly plugin for WordPress is vulnerable to Authorization Bypass via PHP Type Juggling in all versions up to, and including, 28.2. This is due to the `postValidateCustomer()` function using a loose PHP inequality operator (`!=`) to compare the session-stored one-time verification code against the attacker-supplied `verification_code` parameter — a flaw that is further exposed by the booking AJAX controller registering all its methods as `wp_ajax_nopriv_` handlers and unconditionally overriding `csrfTokenValid()` to return true, leaving the endpoint both unauthenticated and CSRF-unprotected. This makes it possible for unauthenticated attackers to bypass the phone/email ownership verification step and overwrite the name, email, phone, and address fields of any arbitrary existing Bookly customer record, redirecting that customer's booking notifications to attacker-controlled contact details. The bypass is achievable because the `json_data` input channel decodes input via `json_decode()`, which preserves real PHP types and causes the `wp_kses` filter to leave non-string values such as the JSON boolean `true` untouched; submitting `true` as the `verification_code` satisfies the loose comparison against the session's non-zero integer code (generated by `mt_rand(100000, 999999)`), causing `true != <non-zero int>` to evaluate as `false` and the guard to be bypassed. |
| The WPForms – AI Form Builder for WordPress – Contact Forms, Payment Forms, Survey Form, Quiz & More plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via 'page_title' POST Parameter via {page_title} Smart Tag in all versions up to, and including, 2.0.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. This is only exploitable on forms whose admin-authored confirmation message places the {page_title} Smart Tag inside an HTML attribute context. |
| The Fancy Product Designer plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'productTitle' in '_fpd_data' Order Item Meta in all versions up to, and including, 6.5.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The fpd_save_order AJAX action is registered for unauthenticated users via wp_ajax_nopriv_fpd_save_order with no nonce or capability check, and the strip_tags() sanitization applied at save time is bypassed by submitting JSON unicode escape sequences (e.g. \u003c, \u003e), which json_decode() silently converts back to literal angle brackets when the order is rendered in the admin view. |
| An attacker with access via network to the Regesta Smart HD-PLC of the provider Teldat (in this case, registration action is required) who has the vulnerable firmware version could inject
a specific payload via the parameter "cmdcookie" withing the /upgrade/index.html resulting in to a Cross-Site Scripting (XSS). This issue affects Regesta Smart HD-PLC - TLDPH16D2:
11.02.06.00.02 |
| The SSL Zen plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'uri' (and 'host') parameters in versions up to, and including, 4.7.42. The ssl_zen_messages::getMessages() function builds the 'token_missmatch' message using base64_decode(sanitize_text_field($_REQUEST['uri'])) and (optionally) base64_decode(sanitize_text_field($_REQUEST['host'])). sanitize_text_field() cannot strip HTML/JavaScript that is hidden inside a base64-encoded blob, and the resulting decoded raw HTML is echoed unescaped by showMessage() . This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a specially crafted link. |
| The Automation Web Platform – Notifications and OTP for WooCommerce, Advanced Country Code plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 4.8.6. This is due to missing permission enforcement on the publicly accessible REST route `POST /wp-json/wawp/v1/signup/<op>` and the absence of a key allowlist in the `finish_registration_logic` function, which copies the attacker-controlled `wawp_custom_fields` parameter directly into `update_user_meta()` — allowing sensitive meta keys such as `wp_capabilities` and `wp_user_level` to be set by the caller. This makes it possible for unauthenticated attackers to register a new account with the administrator role and gain full administrative access to the site. When OTP verification is enabled at signup, the OTP session token (`otp_transient`) is returned in plaintext in the HTTP response body, and the `handle_magic_link_request()` handler marks that token as verified on any unauthenticated GET request containing it without ever checking the OTP code value — making the OTP step trivially bypassable with no inbox or SMS access required. |
| In the Linux kernel, the following vulnerability has been resolved:
mm/madvise: skip device-private PMDs in cold and pageout walks
madvise_cold_or_pageout_pte_range() takes pmd_trans_huge_lock(), whose
pmd_is_huge() check returns true for a device-private PMD. The subsequent
!pmd_present() branch has a VM_BUG_ON() asserting migration is the only
allowed non-present case; a device-private PMD trips it.
Skip device-private PMDs in that non-present branch and continue to
huge_unlock before calling pmd_folio(). Downgrade the check to
VM_WARN_ON_ONCE() so an unexpected PMD softleaf logs a warning rather than
panicking. Drop the thp_migration_supported() guard: it expands to
IS_ENABLED(CONFIG_ARCH_SUPPORTS_PMD_SOFTLEAF), and both
pmd_is_migration_entry() and pmd_is_device_private_entry() already return
false when that config is not selected, so the guard suppresses only the
case where the warning would already be silent.
Potential trigger: an HMM-based GPU driver races with
madvise(MADV_COLD)/MADV_PAGEOUT: pmd_trans_huge(*pmd) reads true, then
migrate_vma_pages() flips the PMD to a device-private entry before the PMD
lock is acquired. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/nouveau/dmem: fix callocated underflow on large folio split
nouveau_dmem_folio_free() drops chunk->callocated once per freed folio,
while a large (compound) device-private folio is only counted once when
it is allocated. When such a folio is split, the mm core invokes
->folio_split() (nouveau_dmem_folio_split()) once for each new
sub-folio, but the hook only fixes up the sub-folio metadata and leaves
chunk->callocated unchanged.
Each resulting sub-folio is later freed separately, so after a split
the single allocation (+1) is met by N frees (-N), leaving
chunk->callocated short by N-1. On the first split/free cycle it
underflows: WARN_ON(!chunk->callocated) fires, the unsigned counter
wraps and never returns to zero, so the chunk can no longer be
reclaimed (nouveau_dmem_fini() also warns on the leaked count).
Account for the new sub-folio in the split hook, under the same lock as
nouveau_dmem_folio_free(), so the count stays balanced. |

Ran: generic/794
Failures: generic/794
Failed 1 of 1 tests
Steps of generic/794:
1. write 4096 bytes to file w/ 0x5a
2. use fiemap to get PBA of first block in file
3. truncate file to 4080
4. umount; write 4096 bytes to file w/ 0x5a directly via PBA; mount
5. extend filesize via
a) append 4096 from offset 4096, or
b) truncate 8192, or
c) fallocate 4096 from offset 4096
6. verify the gap is zeroed in memory [4080,4096)
7. sync range 4096 from offset 4096; shutdown -f (flush meta before shutdown)
8. umount; mount; verify [4080,4096) is zeroed or not.
When extending file size (e.g. via truncate, fallocate, or write) across an
unaligned EOF boundary, we need to ensure that post-EOF data in the partial
page is zeroed out in pagecache and marked dirty, then writeback the cache to
persist zeroed data before committing inode w/ updated i_size.
This help to prevent stale disk data beyond the previous EOF from being exposed
after remounting or crash recovery.
Since f2fs is a LFS filesystem, we only support direct write via PBA in pinfile,
and pinfile has section-aligned filesize, so in Android, there should no problem,
but for other usage in different environment, let's fix this w/ fsync_mode=strict
mount option. |

memcg: bypass the reclaim and oom killer for dying tasks once oom_reaper is done
At Meta, we are seeing instances where an OOM killed job is stuck in the
exit path for several hours. In one particular case, the job was stuck
for more than 8 hours and I had to manually remove the memory.max limits
to allow the process to exit.
The job was a single process job and had ~55 GiB memory.max and zswap
enabled. It had almost 0 anon in memory and ~111 GiB in zswap compressed
to ~51 GiB zswap pool (i.e. almost all of memory.current was zswap).
Nothing was left on the LRUs to reclaim.
On further inspection, I observed ~20k threads of that process stuck with
the following stack:

In addition the dmesg was filled with "Out of memory and no killable
processes..." messages.
I have no idea why oom reaper was not able to reap/unmap the process. My
guess is that since oom reaper tries to acquire mmap_lock in read mode
limited number of times and then gives up, there might be a thread of that
process which had mmap_lock in write mode at that time.
My initial suspicion was the futex_cleanup and kernel page fault causing
infinite fault and charge retries but that was put to rest in previous
discussions happened on similar problem [1].
My current theory is that it is just a simple slow serialization behind
the oom_lock. Unlike page allocator, memcg charge code takes the oom_lock
without the "try". Though memcg oom code uses mutex_lock_killable(), note
that in the call stack get_signal() consumes SIGKILL (or
sigdelset(SIGKILL)) before calling do_group_exit(). So this
mutex_lock_killable() is just a mutex_lock() here. Therefore 10s of
thousands of threads are waiting on oom_lock and one by one they get
-EFAULT from get_user() in the futex cleanup code and bails out.
Discussion from [1] led to commit a75ffa26122b ("memcg, oom: do not bypass
oom killer for dying tasks") which routes dying tasks into the OOM path
precisely so the oom_reaper can reap their mm and free the memory
asynchronously. But the reaper is best-effort and one-shot: if it cannot
take mmap_lock for read (e.g. a sibling thread holds it for write) it
sets MMF_OOM_SKIP and never retries, leaving only the glacial
oom_lock-serialized synchronous drain.
Once MMF_OOM_SKIP is set there is no more asynchronous reclaim coming for
the mm, so a dying task charging against it has nothing left to wait for:
it frees its memory only once it finishes exiting. Running reclaim and
the (no-victim) OOM killer for it is then pointless, and doing it for 10s
of thousands of exiting threads is what serializes them behind oom_lock.
So before reclaim, if current is an OOM victim whose reaper is done, fail
the charge.
Reproduced with 20k threads, each parking a robust futex head on its own
zswapped page, OOM-group-killed while a sibling holds mmap_lock for write
so the reaper gives up and sets MMF_OOM_SKIP. Tested on next-20260728 and
baseline show ~90 seconds exit time while with the patch the exit time
reduced to ~3 seconds. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Fix response queue over-consumption in __qla_consume_iocb()
qla24xx_process_response_queue() advances ring_ptr past the head IOCB
before dispatching, so by the time __qla_consume_iocb() runs, ring_ptr
already points at the first continuation IOCB. The function however
looped purex->entry_count times starting at ring_ptr. As entry_count
includes the head, this consumed one entry too many: it stamped
RESPONSE_PROCESSED on the next, unrelated IOCB and advanced the ring
past it, silently dropping a legitimate firmware response. The head
IOCB's signature was also never marked.
Mark the head processed and account for it, then consume only the
entry_count - 1 continuation IOCBs, matching __qla_copy_purex_to_buffer(). |
| In the Linux kernel, the following vulnerability has been resolved:
mm/secretmem: properly account locked pages
secretmem accounts folios by treating memory as if it were mlock()'d and
thus limited by the RLIMIT_MEMLOCK limit.
However the folios are unevictable and remain so until the inode is
evicted, eliminating usual mlock() semantics - mapping folios then
unmapping them does not clear their unevictable state, since it depends on
AS_UNEVICTABLE, not PG_mlocked.
A user can therefore easily work around the RLIMIT_MEMLOCK limit - simply
map then unmap and VmLck no longer counts the secretmem range. Worse,
folios are not accounted in the process's RSS, meaning the OOM killer
won't know to kill the process.
Repeatedly mapping/unmapping (or forking) can then result in the
consumption of all available system memory with unevictable folios and
cause system instability.
A secretmem fd can be passed between processes and over fork so a
per-process limit simply does not make sense, so follow the precedent set
by io_uring, perf, skbuff, iommufd and xdp by tracking the number of
locked pages in user_struct->locked_vm.
Since the scope tracked is actually inode lifetime, the RLIMIT_MEMLOCK
applies per-user not per-process, so it doesn't make sense to bypass for
users with CAP_IPC_LOCK, therefore remove this bypass.
There is simply no reason to carry on marking the mapping as mlock()'d
since it's misleading and the lifecycle is now correctly handled, so
remove this too.
Note that secretmem does not support any form of truncation (including
hole punching) and the folios are unreclaimable, so the folios need only
be accounted on fault and unaccounted on inode destruction.
__secretmem_account_pages() is more or less a duplicate of the code that
io_uring etc. use, but since this is a bug fix that needs backporting,
defer any de-duplication efforts to a follow-up.
test_mlock_limit() asserts mlock_future_ok() on mmap(), however this has
been removed, so remove the test altogether for the fix. A new test will
be sent separately for upstream. |
