| In the Linux kernel, the following vulnerability has been resolved:
uio: Fix stale info pointer in failed registration path
After device_add(), the UIO device is visible to userspace and /dev/uioX
can be opened. If a later setup step fails, __uio_register_device()
unwinds the device but leaves idev->info pointing at the caller-owned
struct uio_info.
That is unsafe when an opener races with the failed registration path.
The open file keeps a reference to the uio_device, while the caller sees
registration failure and may free its struct uio_info. Later file
operations can then follow idev->info and dereference freed memory.
Handle post-device_add() failures like unregister: remove UIO attributes
while the info pointer is still valid, then clear idev->info under
info_lock and wake existing waiters/async users before removing the
device and minor. This makes already-open file descriptors observe the
same "device gone" state as normal uio_unregister_device(). |
| In the Linux kernel, the following vulnerability has been resolved:
software node: Fix software_node_get_reference_args() with index -1
The bounds check for the index passed to
software_node_get_reference_args() was failing when passed UINT_MAX,
this in turn would lead to an out of bound access in the property
array. Fix the bound check to also cover the UINT_MAX case. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Reject arena frees below the arena base
bpf_arena_free_pages() accepts scalar arena addresses. The runtime
masks the address to the low 32 bits and reconstructs a full user
address from the arena base before returning the range to the arena
free tree.
When the scalar value is below the low 32 bits of the arena base,
full_uaddr falls below user_vm_start. The existing upper-end clipping
then turns this into an out-of-range free-tree offset. A later
allocation can reuse that offset and return an address below the arena
mapping.
Reject such frees before computing the clipped range. |
| In the Linux kernel, the following vulnerability has been resolved:
dmaengine: dw-edma: Terminate all descriptors without callbacks
The DMA Engine client documentation says in the "Terminate APIs" section
of Documentation/driver-api/dmaengine/client.rst:
"No callback functions will be called for any incomplete transfers."
dw-edma instead calls vchan_cookie_complete() when a deferred STOP reaches
the interrupt handler. This schedules a callback for the active descriptor
and leaves other issued or submitted descriptors queued. A late callback
after dmaengine_terminate_sync() can dereference client state that has
already been freed, while leftover descriptors may later restart into
reused buffers or leak.
Move all issued and submitted descriptors to the terminated list whenever
termination completes. For a pending STOP, do this from both the DONE and
ABORT paths. Complete their cookies in order without scheduling callbacks.
A STOP can remain pending until the running transfer raises an
interrupt. Make device_synchronize() wait for such a pending STOP to
complete before releasing terminated descriptors. Reuse it from
free_chan_resources(), then release the remaining virt-dma resources.
Sleep instead of busy-polling while waiting, and warn if the existing
timeout expires. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: meson: Keep link pointers valid on realloc failure
meson_card_reallocate_links() grows the DAI link and private data
arrays with two consecutive krealloc() calls and updates the owner
pointers only after both calls have succeeded.
A successful krealloc() may move the data: it frees the old block and
returns a new one. When that happens for the link array and the second
krealloc() then fails, card->dai_link still points to the block that
krealloc() already freed, and the error path frees the new block too.
The probe error path then calls meson_card_clean_references(), which
dereferences card->dai_link and kfree()s it again, resulting in a
use-after-free and a double free.
Commit card->dai_link and card->num_links right after the first
krealloc() succeeds, so the pointer always refers to a valid allocation
that meson_card_clean_references() can walk and free. krealloc() with
__GFP_ZERO zero-initializes the added entries, so walking them on the
error path is safe. With both failure paths reduced to a plain return,
drop the goto labels and the error message. |
| In the Linux kernel, the following vulnerability has been resolved:
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.
Found by Linux Verification Center (linuxtesting.org) with SVACE. |
| Imager versions before 1.036 for Perl exit the process reading a TGA with a colour map length of 32768 or more in tga_palette_read.
The reader unpacks the two-byte colour map length into a signed short, so a length of 32768 or more becomes negative. tga_palette_read() casts that value to size_t and asks mymalloc() for a size near SIZE_MAX. The allocation fails and Imager's allocator calls exit(3).
Reading an attacker-supplied file through Imager->read() triggers an uncatchable exit. |
| HortusFox-Web prior to version 6.1 contains a remote code execution vulnerability that allows authenticated administrators to execute arbitrary OS commands as the web server user by abusing the Import/Export functionality. Attackers can leverage the Import/Export feature, which is intended solely for data portability, to deploy and execute malicious code on the underlying application server host. |
| Cocos AI is a confidential computing system for running AI workloads inside trusted execution environments. In versions up to and including 0.8.2, the intra-handshake attested TLS (aTLS) AMD SEV-SNP verification path does not enforce attestation freshness when the expected reportData value is nil, empty, or omitted, leaving the SEV-SNP policy ReportData unset so the verifier accepts unrelated or stale Evidence not bound to the current connection. A relying party that uses this path without an expected reportData as a trust or authorization decision can be induced to trust an unintended attestation context; a supplied non-empty reportData is still validated. The issue is fixed in version 0.9.0. |
| ContiNew Admin through 4.1.0 contains an authorization bypass vulnerability in the personal message delete endpoint that allows authenticated users to delete other users' messages and announcements. Attackers can supply arbitrary message identifiers in the IdsReq parameter to remove any message row and purge all recipients' read receipts without ownership validation. |
| reNgine through 2.2.0 contains an authorization bypass vulnerability in the GetFileContents API endpoint that allows any authenticated user to read bundled recon tool configuration files. Attackers with low-privilege Auditor roles can access files containing third-party API keys for services like SecurityTrails, Shodan, Censys, VirusTotal, BinaryEdge and Hunter by querying the endpoint without role-based permission checks. |
| Rallly before 4.15.0 contains an information disclosure vulnerability in the polls.get tRPC procedure that returns scheduled-event invitee names and email addresses to unauthenticated callers. Attackers can access a poll's urlId from public invite links to retrieve sensitive invitee information regardless of privacy settings. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/rxe: Validate num_sge/cur_sge before indexing wqe->dma.sge[]
For a user QP, qp->sq.queue is a ring the application writes directly,
so rxe_post_send() takes the is_user branch and only schedules send_task
without validating the WQE. rxe_requester() consumes it in place via
req_next_wqe() and calls copy_data(), which indexes
&wqe->dma.sge[cur_sge] with the attacker-controlled num_sge/cur_sge.
Only the kernel path bounds num_sge (validate_send_wr()); the user WQE
is never checked, so a local unprivileged user can post a WQE with an
out-of-range cur_sge or oversized num_sge and force an out-of-bounds
read of the per-WQE sge array in copy_data() (vmalloc OOB read, local
DoS).
Bound num_sge to qp->sq.max_sge in rxe_requester() before use, the way
get_srq_wqe() already guards SRQ entries, and bound cur_sge only when
the WQE carries payload (dma.resid): copy_data() returns early on a
zero-length copy before touching dma->sge[], so a zero-payload WQE --
the only kind a max_sge == 0 QP can post -- stays valid.
Reproduced under KASAN; the vmalloc-out-of-bounds in copy_data() is gone. |

ACPI: processor: validate MADT IOAPIC entry bounds
The IOAPIC hotplug lookup parses both MADT and _MAT records directly.
The MADT walk previously used a subtable's declared length to advance
the cursor after only locating a generic header. The _MAT path likewise
passed a generic header to the IOAPIC helper.
Validate that a current record has a complete generic header, that its
declared length is contained in the available record range, and that a
typed IOAPIC record contains the full fixed IOAPIC body before reading
its fields. Use the same relation for both MADT and _MAT provider
paths. |
| In the Linux kernel, the following vulnerability has been resolved:
riscv, bpf: Fix kernel stack corruption in tailcall with CFI
When CONFIG_CFI_CLANG is enabled, prog->bpf_func already skips the kcfi
instruction during setup. Including it again in the tailcall jump offset
causes it to jump over an extra 4 bytes, skipping the stack pointer
adjustment, which will result in kernel stack corruption. |
| In the Linux kernel, the following vulnerability has been resolved:
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. |

| 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. |
