CVSS v3.1 |
| GitLab has remediated an issue in GitLab CE/EE affecting all versions from 18.6 before 19.1.8, 19.2 before 19.2.6, and 19.3 before 19.3.2 that under certain conditions could have allowed an authenticated user to bypass SAML SSO sign-in restrictions and authenticate without SSO due to missing authentication enforcement checks. |
| IBM Cloud Pak for Business Automation is vulnerable to stored cross-site scripting. This vulnerability allows an authenticated user to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session. |
| IBM Verify Identity Access could allow an administrator to execute additional commands they are not entitled to due to improper validation of user supplied requests. |
| IBM Security Verify Identity Access reverse proxy may allow parameters to be injected in requests to third party services. |
| IBM ContextForge MCP Gateway <= v1.0.4 IBM mcp-context-forge could allow an authenticated user to bypass protection mechanisms due to incomplete recursive inspection of nested payload content. |
| Froxlor before 2.2.0 (affected up to and including 2.2.0-rc3) generates /etc/pure-ftpd/db/mysql.conf with mode 0644 via the XML configuration templates in lib/configfiles/, even though the file contains the Froxlor SQL user's password. On systems where the parent directories are world readable (the default on Debian 12), any unprivileged local user able to execute commands or code on the host — including virtual users without SSH access who can upload PHP/CGI scripts — can read the file and obtain the Froxlor database credentials. Database access can then be leveraged to alter an administrator's password hash and TOTP seed, log in as a Froxlor administrator, and ultimately gain root privileges. Only instances configured to use pure-ftpd are affected. |
| A vulnerability was found in D-Link R95 BE9500_1.00.16. This vulnerability affects the function system of the file /bin/ssi of the component DHMAPI. The manipulation of the argument NTPServer results in os command injection. The attack can be executed remotely. The exploit has been made public and could be used. |
| In the Linux kernel, the following vulnerability has been resolved:
nvme-apple: Destroy the admin queue on removal
The admin queue is allocated with blk_mq_alloc_queue() but never
destroyed. nvme_free_ctrl() only drops the last reference and
blk_mq_exit_queue() and blk_sync_queue() never run: the hctx is never
moved to q->unused_hctx_list and the timeout timer and work stay armed on
a queue that is about to be freed which will eventually oops inside
blk_mq_timeout_work().
This can only be triggered when the controller fails to come up and is
then immediately torn down again which is why no one ever ran into this
before.
Let's just copy what the pcie driver does: unquiesce and destroy the admin
queue before nvme_uninit_ctrl().
With this the following WARN followed by a panic no longer happens:

| In the Linux kernel, the following vulnerability has been resolved:
nvmet: fix heap out-of-bounds read in nvmet_auth_negotiate()
nvmet_execute_auth_send() allocates the DH-HMAC-CHAP message buffer with
the host-supplied transfer length (tl) and hands it to
nvmet_auth_negotiate() without passing tl along. nvmet_auth_negotiate()
then reads the negotiate header and, for each of the halen hash
identifiers and dhlen DH group identifiers, indexes into the fixed
idlist[60] array (hashes at idlist[0..halen), groups at idlist[30..]).
Neither the transfer length nor halen/dhlen is validated. A malicious or
non-conformant host can report a tl smaller than the negotiate structure,
or a halen/dhlen larger than the array (both are u8, up to 255), making
the loops read past the end of the allocated buffer (heap out-of-bounds
read). The sibling nvmet_auth_reply() already validates tl against the
structure size; the negotiate path did not.
Pass tl into nvmet_auth_negotiate(), reject a tl that does not cover the
negotiate data plus one full protocol descriptor, and reject halen/dhlen
larger than NVME_AUTH_DHCHAP_MAX_DH_IDS. |
| In the Linux kernel, the following vulnerability has been resolved:
apparmor: fix unconfined user namespace restriction forced stack
If a task is already confined by a stack the unprivileged transition
restriction on unconfined is not correctly, applied. This results in
an escape if two transitions through an unconfined profile can be
executed.
Fix this by pushing the check into the per profile label build. The
check will always be done against unconfined and result in a stack of
just the unconfined component when necessary. |
| In the Linux kernel, the following vulnerability has been resolved:
sunrpc: xprtsock: annotate shared socket callbacks with READ_ONCE/WRITE_ONCE
xprtsock replaces and restores sk->sk_data_ready and
sk->sk_write_space on live sockets with plain stores, and
xs_udp_do_set_buffer_size() invokes sk->sk_write_space via a plain
load. These callback pointers are shared with generic socket and
protocol paths that may read or invoke them concurrently, so xprtsock
needs the same READ_ONCE()/WRITE_ONCE() callback visibility contract
that the validated 4022 family applied elsewhere.
When SUNRPC takes over an AF_LOCAL, UDP, or TCP socket and later
restores the lower-socket callbacks during teardown, another CPU may
still hold an earlier callback snapshot. The plain replace/restore
pattern leaves the same visibility hole as the validated 4022 family,
so a stale snapshot can still invoke xs_data_ready() or
xs_udp_write_space() after the live callback fields have already been
restored to the lower-socket handlers.
Use WRITE_ONCE() for the shared sk_data_ready and sk_write_space
stores in xs_local_finish_connecting(), xs_udp_finish_connecting(),
xs_tcp_finish_connecting(), and xs_restore_old_callbacks(). Use
READ_ONCE() for the direct sk_write_space invocation in
xs_udp_do_set_buffer_size(). This matches the required callback
visibility contract while leaving adjacent sk_state_change and
sk_error_report handling unchanged. |
| In the Linux kernel, the following vulnerability has been resolved:
iommu/vt-d: Flush context cache with correct SID when tearing down aliases
domain_context_clear_one() and device_pasid_table_teardown() are both
invoked once per DMA alias of a device. Each function locates the context
entry using the bus/devfn pair provided by the pci_for_each_dma_alias()
callback, then calls intel_context_flush_no_pasid(), which constructs a
device-selective context-cache invalidation from info->bus and
info->devfn (that is, always the requester ID of the device itself).
As a result, for every alias other than the device’s own RID, the context
entry that was just cleared in memory is never invalidated in the context
cache. Hardware may continue using that stale cached entry. In the
scalable-mode teardown path, intel_pasid_free_table() can then free the
PASID directory still referenced by that stale entry, allowing the IOMMU
to walk freed memory.
Fix this by passing the source ID of the entry being torn down to
intel_context_flush_no_pasid(), instead of deriving it from @info. |
| In the Linux kernel, the following vulnerability has been resolved:
iommu/vt-d: Tear down scalable-mode context on probe failure
intel_pasid_setup_sm_context() walks a PCI device’s DMA aliases via
pci_for_each_dma_alias() and programs a scalable-mode context entry for
each RID. For a device with a dma_alias_mask, the callback is invoked
once for the device’s own RID and once for each alias bit, all with the
same pci_dev, so device_pasid_table_setup() runs for multiple RIDs.
pci_for_each_dma_alias() stops at the first callback error. Therefore, a
failure partway through the walk can leave context entries for already
processed RIDs present and still pointing to the device’s PASID table.
On this error path, intel_iommu_probe_device() currently jumps directly
to intel_pasid_free_table(), which frees the PASID table without
first tearing down those context entries. The IOMMU may then walk a
present context entry whose PASID table pointer references freed
memory.
intel_iommu_release_device() already performs teardown before freeing the
table. Apply the same ordering on the probe failure path.
device_pasid_table_teardown() safely handles RIDs that were never
programmed: iommu_context_addr() returns NULL when no context table has
been allocated, and clearing the Present bit of an already non-present
entry is a no-op. So unwind is safe for both the alias that failed and
any aliases not yet reached. |
| In the Linux kernel, the following vulnerability has been resolved:
iommu/vt-d: Clear Present bit before tearing down copied context entry
copied_context_tear_down() zeroes the 128-bit context entry with
context_clear_entry() while the Present bit is still set, and only then
issues the context-cache and IOTLB invalidations. This leaves a window
in which hardware can fetch a torn entry, with some fields already zeroed
while Present is still set, leading to unpredictable behaviour or
spurious faults. While x86 provides strong write ordering, the compiler
may reorder the writes to the two 64-bit halves of the entry, and the
hardware fetch is not guaranteed to be atomic with respect to multiple
CPU writes.
There is no cacheline flush before the invalidation either, so on an
IOMMU without coherent access to the context table the zeroed entry may
not be visible to hardware at the point the invalidation is submitted.
Apply the same ownership handshake described in the VT-d spec, Section
6.5.3.3 ("Guidance to Software for Invalidations"): clear only the Present
bit, flush it out to the IOMMU, perform the invalidations, and only then
zero the remainder of the entry. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix mmap_lock leak in irq_work path
stack_map_get_build_id_offset() introduced a per-CPU irq_work to defer
mmap_read_unlock() from NMI context, and bpf_find_vma() later reused the
same mmap_unlock_work. Both callers only check whether the work is busy
before taking mmap_lock, so a nested caller can reuse the slot before the
first caller queues it. Two read locks may then be acquired while only one
deferred unlock runs, leaking a read lock and blocking exit_mmap().
Reserve the per-CPU slot before mmap_read_trylock(). Use the same wrapper
in stackmap and bpf_find_vma() so both callers release the reservation on
trylock failure. Keep rejecting the slot while the irq_work remains busy.
Release it after the irq_work callback unlocks the mm. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_conn: fix the SCO setup context lifetime
hci_setup_sync() queues a conn_handle_t with a NULL destroy callback, so
the context is only freed if hci_enhanced_setup_sync() actually runs. An
entry that is cancelled instead is leaked, as
_hci_cmd_sync_cancel_entry() does not release entry->data when there is
no destroy callback, and hci_cmd_sync_clear() cancels every pending entry
when the controller is unregistered.
The context also stores a bare hci_conn pointer, so the connection can be
freed while the work is queued. The dequeue in hci_conn_del() does not
cover it either, as it matches on entry->data == conn and entry->data is
the wrapper here. Same problem as commit 2f5d635ad590 ("Bluetooth:
hci_sync: hold conn in hci_connect_acl/le_sync() callbacks").
Hold the connection and release both from a destroy callback. The
submission failure path drops both, since hci_cmd_sync_submit() does not
call the destroy callback when it fails to queue. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: L2CAP: use proto_lock for l2cap_data to fix l2cap_disconn_ind
hci_conn::l2cap_data is accessed without locks in l2cap_disconn_ind via
hci_conn_timeout (disc_work) -> hci_proto_disconn_ind ->
l2cap_disconn_ind. This is UAF if the l2cap_conn is deleted
concurrently.
disc_work is disabled sync in hci_conn_del(), so we cannot take
hci_dev_lock in disc_work.
Fix by using proto_lock to guard l2cap_data, in addition to hdev->lock
which is held in other access paths. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: virtio_bt: avoid OOB read of build info string
The virtbt_setup_zephyr() sends the Zephyr vendor command 0xfc08 (Read
Build Information) and hands the response to bt_dev_info() and
hci_set_fw_info() as a "%s" string starting at skb->data + 1, without
checking the length. A backend that answers with status only leaves that
pointer past the end of the received data, so the walk reads adjacent
slab memory until it meets a NUL. Those bytes reach the kernel log and
the firmware-info debugfs file.
To fix this, print the string with a bounded "%.*s" limited to
skb->len - 1. A short or unterminated response then prints as much as
arrived instead of failing setup.
This mirrors commit dd068ef04412 ("Bluetooth: bpa10x: avoid OOB read of
revision string in bpa10x_setup()"), which fixed the identical pattern. |
| In the Linux kernel, the following vulnerability has been resolved:
btrfs: zoned: don't clobber the extent buffer when zeroing it out
On a zoned filesystem a freed-but-still-dirty tree block is written out
as zeros (EXTENT_BUFFER_ZONED_ZEROOUT) only to keep the zone write
pointer advancing. btree_csum_one_bio() implemented this by memzeroing
the extent buffer's own folios before submission.
That destroys the in-memory buffer while it may still be referenced. In
particular btrfs_free_tree_block() can run on it afterwards and reads
the header to add a delayed reference; once the header has been zeroed
it frees bytenr 0 and corrupts the extent tree (the
btrfs_header_bytenr(buf) != 0 ASSERT in btrfs_free_tree_block(), or an
"unable to find ref" abort). It is flaky and reproduces under fsstress,
e.g. generic/461 and generic/013.
Write the zeros to disk from the shared zero page instead and leave the
extent buffer content untouched, so any later reference - including the
delayed reference from btrfs_free_tree_block() - still sees a valid
header. end_bbio_meta_write() now clears writeback on the buffer's own
folios, as the bio no longer carries them. |
| In the Linux kernel, the following vulnerability has been resolved:
arm_mpam: Disable driver unbind to avoid UAF
When a user unbinds an MSC and that MSC is the only MSC left for a
component then the corresponding mpam_component will be freed. If the user
then goes on to read the schemata file in the resctrl filesystem then the
mpam_component will be accessed from resctrl_arch_get_config() leading to a
use after free.
As the MPAM driver is not a module the unbind sysfs interface is the only
way to trigger the remove. Instead of dealing with the complexity of
allowing some unused MSC to unbind just remove the unbind sysfs interface. |
