bpf: Fix WARNING in bpf_tracing_link_release
The trampoline could be corrupted by the blindly
'tr->flags = BPF_TRAMP_F_TAIL_CALL_CTX' in verifier.
1. A fexit attached to a tail_call_reachable prog. 'tr->flags' became
'BPF_TRAMP_F_CALL_ORIG | BPF_TRAMP_F_TAIL_CALL_CTX'. And, the
trampoline would poke the target prog's nop insn using jmp insn instead
of call insn.
2. Another fexit loaded with the same tail_call_reachable prog target.
'tr->flags' became 'BPF_TRAMP_F_TAIL_CALL_CTX'.
3. Close the first fexit link. Due to no BPF_TRAMP_F_CALL_ORIG in
'tr->flags', the trampoline will fail to restore the prog's nop insn
using call insn.

| In the Linux kernel, the following vulnerability has been resolved:
HID: core: quiesce input in hid_hw_stop() to prevent use-after-free
A driver's probe calls hid_device_io_start() to enable input delivery,
then fails at a later initialization step and unwinds via hid_hw_stop().
The unwind frees struct hidraw via hidraw_disconnect() while in-flight
HID reports may still be running on another CPU, dereferencing the
freed object through hidraw_report_event(). syzbot reports the
resulting use-after-free for the corsair-psu HID driver.
Edward Adam Davis posted a per-driver fix for corsair-psu that adds
an explicit hid_device_io_stop() before hid_hw_stop() in the probe
error path ("hwmon: prevent packets from going to driver for probe",
2026-04-28). Auditing the tree shows 15 drivers call
hid_device_io_start(); 7 also call hid_device_io_stop() and 8 do not:
drivers calling hid_device_io_start() without a matching
hid_device_io_stop() before hid_hw_stop():
drivers/hwmon/corsair-psu.c (fix posted by Edward)
drivers/hwmon/corsair-cpro.c
drivers/hwmon/nzxt-kraken3.c
drivers/hwmon/nzxt-smart2.c
drivers/hwmon/gigabyte_waterforce.c
drivers/hid/hid-logitech-dj.c
drivers/hid/hid-nintendo.c
drivers/hid/hid-mcp2221.c
Roughly half of all callers of the API are exposed. Centralize the
quiesce in hid_hw_stop() so callers do not have to remember the
matching stop: if a driver has left hdev->io_started true on entry,
call hid_device_io_stop() before hid_disconnect().
For the 7 drivers that already call hid_device_io_stop() correctly,
hdev->io_started is false on entry, the guard short-circuits, and
behavior is unchanged.
No Fixes: tag because the affected drivers gained their
hid_device_io_start() calls independently over years; the bug is a
class-wide API misuse rather than a regression from one commit. |
| The LiteSpeed Cache plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'esi' parameter in all versions up to, and including, 7.9 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. Exploitation requires that the attacker supply a validly signed 'esi' value in the GET query string while submitting a separate attacker-controlled 'esi' payload as a POST body field, relying on PHP's default $_REQUEST merge order to have the POST value take precedence at the point of execution. |
| A vulnerability has been found in olivier-ls PHP-FTS up to 1.1.3. This affects the function SearchEngine::matchesSingleFilter of the file src/SearchEngine.php of the component Filter Matching. The manipulation leads to incorrect comparison. Remote exploitation of the attack is possible. The exploit has been disclosed to the public and may be used. Upgrading to version 1.1.4 is able to mitigate this issue. The identifier of the patch is 0b2fae333d6b022da7ed4c43e2d41aa03f91dff3. It is suggested to upgrade the affected component. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Check load-acquire src ptr type before the load
check_atomic_load() calls check_load_mem() before atomic_ptr_type_ok().
For a load-acquire that fetches into its own source register (dst_reg ==
src_reg), check_load_mem() overwrites src_reg's type with the type of the
loaded value, so the subsequent atomic_ptr_type_ok() no longer sees the
source pointer and fails to reject the disallowed types (ctx, pkt,
flow_keys, sock).
Since bpf_convert_ctx_accesses() does not rewrite atomic loads, the raw
access to the underlying kernel object is left in place. The destination
type is taken from the ctx access itself, so a load-acquire of the sk
field of struct __sk_buff for example leaves the register typed as
PTR_TO_SOCK_COMMON_OR_NULL, which type_is_sk_pointer() does not match
either, while it actually holds unconverted struct sk_buff bytes. Once
the NULL check has passed this is a type confusion, not just a leak of
kernel data.
Validate src_reg with check_reg_arg() and check the source pointer type
with atomic_ptr_type_ok() before the load again, mirroring
check_atomic_rmw(). Out-of-range register numbers are already rejected
earlier by check_and_resolve_insns() (commit 503d21ef8eac ("bpf: Do
register range validation early")), and the only exemption there,
is_stack_arg_ldx(), requires BPF_LDX | BPF_MEM | BPF_DW and thus never
matches a BPF_ATOMIC insn. atomic_ptr_type_ok() can therefore not
dereference register state out of bounds, that is, the out-of-bounds
read addressed by the Fixes commit below does not reappear (as proven
also via selftest). |
| In the Linux kernel, the following vulnerability has been resolved:
md: remove REQ_NOWAIT support from raid1/10/456
REQ_NOWAIT support in md personalities that can block internally is
fundamentally incomplete. While reads can avoid some blocking paths,
write requests can still encounter cases where one mirror succeeds while
another returns -EAGAIN. At that point md cannot distinguish queue
pressure from a real device failure, so it can neither record a bad
block nor safely retry the write without REQ_NOWAIT, leaving mirrors
with divergent data.
Rather than continue advertising REQ_NOWAIT support for personalities
that cannot implement it correctly, remove it from raid1, raid10 and
raid456. Keep REQ_NOWAIT for linear and raid0, which only remap bios to
their underlying devices; stacked limits will still clear the feature if
any component device lacks REQ_NOWAIT support. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: fix overreads in ath11k_wmi_process_csa_switch_count_event()
There is no policy entry for WMI_TAG_PDEV_CSA_SWITCH_COUNT_STATUS_EVENT, so
the parse infrastructure does not enforce a minimum length for the event
struct. Additionally, the num_vdevs field is taken directly from firmware
and used as a loop bound over the vdev_ids array without checking that it
fits within the TLV payload. Either condition can cause an out-of-bounds
read.
Add a TLV policy entry for WMI_TAG_PDEV_CSA_SWITCH_COUNT_STATUS_EVENT so
the parse infrastructure enforces a minimum length for the fixed-size event
struct. Add a helper ath11k_wmi_tlv_data_len() to recover the payload
length of a parsed TLV from the header preceding its data pointer. Use it
in ath11k_wmi_process_csa_switch_count_event() to bound num_vdevs before
the loop.

RDMA/rxe: Fix UAF in ODP init error-handling path
rxe_odp_mr_init_user() stores &umem_odp->umem in mr->umem before
calling rxe_odp_init_pages(). If rxe_odp_init_pages() fails,
rxe_odp_mr_init_user() releases umem_odp and returns an error.
rxe_reg_user_mr() then unwinds the error through rxe_cleanup(),
rxe_mr_cleanup(), ib_umem_release(mr->umem). There is an
IS_ERR_OR_NULL(umem) check at the start of ib_umem_release().
But since mr->umem is NOT reset to NULL in the error handling
path of rxe_odp_mr_init_user(), the check passes and it reads
already-freed fields like umem->is_dmabuf, causing UAF.
Fix the UAF by clearing mr->umem after releasing the failed
ODP umem so the MR cleanup path does not release it again. |

RDMA/hfi1: Propagate sdma_txinit_ahg() errors
set_txreq_header_ahg() ignores the return value of sdma_txinit_ahg().
If sdma_txinit_ahg() fails, it returns before initializing tx->txreq.
However, set_txreq_header_ahg() ignores the error and returns the AHG
change count, causing the caller to continue processing the request as
though initialization had succeeded.
Propagate sdma_txinit_ahg() failures to the caller and abort request
processing when initialization fails.

platform/x86: asus-wmi: fix resource leaks on probe failure
During driver initialization in asus_wmi_add(), various subsystems are
registered sequentially. However, the error path labels are out of order
relative to the registration sequence.
Specifically:
1. If asus_wmi_custom_fan_curve_init() fails, the driver jumps to
fail_custom_fan_curve. Because this label is placed below fail_sysfs,
it bypasses the cleanup calls for the input device and sysfs groups,
which were successfully registered before, leaking those resources.
2. If asus_screenpad_init() fails, the driver jumps to fail_screenpad.
Because fail_screenpad is placed below fail_backlight, it bypasses the
cleanup calls for backlight and rfkill, leaking those resources.
Fix these resource leaks by reordering the error path labels in
asus_wmi_add() to match the exact reverse order of the resource
allocations. |

Return -EINVAL when any index is out of range. |
| The Mailchimp for WooCommerce WordPress plugin before 6.1.1 does not verify that the requesting user holds the required capability in the permission callback for several of its REST API routes, allowing unauthenticated users to reach administrator-oriented endpoints and trigger a persistent state change. |
| Argo Workflows versions 4.1.0 through 4.1.3 contain an authorization bypass vulnerability in ListArchivedWorkflows that fails to apply cluster-scoped access review when the metadata.namespace field selector uses the NotEquals operator. Attackers with namespace-scoped list permissions can use a negated namespace field selector to retrieve archived workflows from all other namespaces, exposing spec arguments, parameter values, and annotations. |

arm64: ptrace: Keep 'orig_x0' in-sync with x0 on syscall entry
Commit e057b9477232 ("arm64: syscall: Ensure saved x0 is kept in-sync
with tracer updates") attempted to resolve a long-standing issue with
syscall entry tracing, where a tracer is able to manipulate the first
syscall argument without being subjected to seccomp or audit checking.
Unfortunately, that fix was incomplete [1], as it failed to update
'orig_x0' between a tracer updating x0 during a seccomp ptrace exit
(SECCOMP_RET_TRACE) and the seccomp filter being re-evaluated.
Rather than add hooks to the core seccomp code, instead move the
synchronisation code into the ptrace GPR and syscall setting code so
that 'orig_x0' is kept up to date with x0 whenever we're stopped on the
syscall entry path. |

iommu/tegra241-cmdqv: Don't fall back to a freed smmu after devm_krealloc()
__tegra241_cmdqv_probe() uses devm_krealloc() to grow @smmu into the larger
tegra241_cmdqv, which frees the original @smmu once it relocates. A failure
after that returned NULL, and the caller then dereferenced the freed @smmu
on its fallback path.
Return an int and take @smmu by reference instead, then update *smmu to the
reallocated pointer after devm_krealloc() succeeds, so the caller and its
fallback path both use the live @smmu rather than the freed original. |
| In the Linux kernel, the following vulnerability has been resolved:
iommu/tegra241-cmdqv: Synchronize the error ISR against VINTF (de)init
A user VINTF is torn down by tegra241_cmdqv_deinit_vintf(), which runs from
the destroy callback and from the init-failure unwind in the alloc handler.
It clears the cmdqv->vintfs[] slot and lets the iommufd core free it, but
nothing serializes that against the error interrupt: tegra241_cmdqv_isr()
reads cmdqv->vintfs[idx] and dereferences the vintf. A concurrent error can
make the ISR read a slot mid-clear (a NULL deref) or use a vintf which is
about to be freed (a use-after-free).
deinit_vintf() also returns idx to the IDA before clearing the slot, so a
concurrent create that reuses idx can publish its new vintf into the slot,
only for this teardown to erase it again with the stale NULL store.
On the other end, tegra241_cmdqv_init_vintf() publishes a new vintf with a
plain store to the cmdqv->vintfs[] slot, and the ISR dereferences fields of
a published vintf such as vintf->base. A plain store gives no ordering on a
weakly-ordered CPU, and a stale VINTF_ERR_MAP bit on a reused idx can make
the ISR pick a vintf the moment it is published, before its fields are set
or tegra241_vintf_hw_init() runs.
The cmdqv->vintfs[0] slot stays NULL until tegra241_cmdqv_init_structures()
first creates VINTF0, so the slot 0 read needs the same NULL check.
Publish every slot with an smp_store_release(), and read each slot in the
ISR with an smp_load_acquire() under a NULL check, so the ISR always sees
a fully built vintf or NULL. Also make deinit_vintf() clear the slot, and
synchronize_irq() prior to returning idx to the IDA, so no vintf is freed
under a running handler and no reused idx is clobbered. |
| In the Linux kernel, the following vulnerability has been resolved:
thermal: intel: int3400: clean up ODVP on probe failures
evaluate_odvp() creates per-ODVP sysfs files before the thermal zone
and later probe resources are registered. The current unwind path only
calls cleanup_odvp() from the late sysfs failure path, so failures after
evaluate_odvp() but before that label, including
thermal_tripless_zone_device_register() failures, leave the ODVP files
and storage behind.
Move the ODVP cleanup to the common ART/TRT unwind path so every failure
after evaluate_odvp() releases the ODVP state. Also clear the cached
ODVP pointers in cleanup_odvp(), because evaluate_odvp() can already call
it for partial setup failures while probe continues. |

RDMA/core: Fix potential use after free in ib_destroy_cq_user()
When accessing a CQ via the netlink path the only synchronization
mechanism for the said CQ is rdma_restrack_get().
Currently, rdma_restrack_del() is invoked at the end of
ib_destroy_cq_user(), which is too late, since by that point
vendor-specific resources associated with the CQ might already be
freed. This can leave a short window where the CQ remains accessible
through restrack, leading to a potential use-after-free.
Fix this by moving the rdma_restrack_begin_del() call to the start of
ib_destroy_cq_user(), ensuring that the CQ is removed from restrack
before its internal resources are released. This guarantees that no new
users hold references to a CQ that is in the process of destruction.
In addition, this change preserves the intended inverted order
between create and destroy routines: resources are added to
restrack at the end of successful creation, and hence shall be removed
from the restrack first thing during the destruction flow, which keeps
the lifecycle management consistent and predictable. |
