| In the Linux kernel, the following vulnerability has been resolved:
drm/gpusvm: Reject VMAs with VM_IO or VM_PFNMAP when creating SVM ranges
VMAs marked with VM_IO or VM_PFNMAP are not backed by struct page
objects, which GPUSVM requires in order to operate correctly. In
particular, get_pages() relies on hmm_range_fault() to resolve struct
pages for the target range.
Attempting to create an SVM range on such VMAs results in repeated
get_pages() failures and can lead to an infinite loop inside a driver’s
page‑fault handler. Prevent this by rejecting ranges on VM_IO or
VM_PFNMAP VMAs and returning -EIO. |
| In the Linux kernel, the following vulnerability has been resolved:
accel/amdxdna: Fix leak when pinning ubuf pages
When pin_user_pages_fast() returns fewer pages than requested, the pages
that were successfully pinned are not released, leading to a leak.
Fix this by unpinning any partially pinned pages before returning failure. |
| In the Linux kernel, the following vulnerability has been resolved:
afs: handle CB.InitCallBackState3 requests without a server record
The cache manager callback path now attaches the server record to an
incoming call through the rxrpc peer's app data. That association is
not guaranteed to exist for every callback request, and most callback
handlers already tolerate that case.
Make CB.InitCallBackState3 follow the same pattern by checking whether a
server record was attached before using it. If the peer is not mapped
to a server record, trace the request and ignore it, matching the
existing behaviour for other unmatched callback requests.
This keeps the callback handler consistent with the rest of the cache
manager service and avoids depending on peer state that may not be
available for a given request. |
| In the Linux kernel, the following vulnerability has been resolved:
afs: fix NULL pointer dereference in afs_get_tree()
afs_alloc_sbi() uses kzalloc for memory allocation. And, if
ctx->dyn_root is not null, as->cell and as->volume are null.
In trace_afs_get_tree() they are dereferenced.

| In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: fix use-after-free in ump_to_endpoint()
create_midi2_ump() registers a card-owned snd_ump_endpoint and stores a
back-pointer to its per-interface snd_usb_midi2_ump object in
ump->private_data, but it never installs an ump->private_free hook and
never clears that pointer.
If a later step of snd_usb_midi_v2_create() fails, its error path calls
free_all_midi2_umps(), which kfree()s the snd_usb_midi2_ump object while
the already-registered endpoint keeps pointing at it. The created
/dev/snd/umpC*D* node stays exposed, so the first operation of any UMP
open, ump_to_endpoint(), dereferences the dangling ump->private_data and
reads rmidi->eps[dir] out of freed memory.
A malicious USB MIDI 2.0 device that makes creation fail after the
endpoint is registered can thus trigger a slab use-after-free read on a
subsequent open of the UMP node.
Clear the endpoint's back-pointer before freeing the object, and let
ump_to_endpoint() tolerate a NULL private_data so the open/close/trigger
callbacks fail cleanly (their callers already handle a NULL endpoint)
instead of dereferencing a stale pointer.

| @fastify/oauth2 is an OAuth 2.0 plugin for Fastify. In versions from 7.2.0 up to but not including 8.3.0, the plugin validates the OAuth state, and with PKCE the code verifier, by comparing the callback query parameter against an unprefixed, predictable cookie, with no server-side binding to the browser that began the flow. Any party able to write a cookie for the application's host, such as a sibling subdomain under the same registrable domain, can plant matching state and verifier cookies and complete an attacker-owned OAuth flow inside a victim's browser, silently signing the victim in to the attacker's account (login CSRF). It does not expose the victim's own account, credentials, or tokens. The issue is fixed in @fastify/oauth2 8.3.0, which adds an opt-in hostPrefixedCookies option. Users should upgrade to 8.3.0 and enable it, or bind state to a server-side session. |

v2: move resume_all after remove |
| In the Linux kernel, the following vulnerability has been resolved:
afs: Fix netns teardown to cancel the preallocation charger
Fix the teardown of an afs network namespace to make sure it cancels the
work item that keeps the preallocated rxrpc call/conn/peer queue charged
before incoming calls are disabled (i.e. listen 0).
Also, if net->live is false because the afs netns is being deleted, make
afs_charge_preallocation() skip charging and make afs_rx_new_call() avoid
requeuing the charger.
(This was found by AI review). |
| In the Linux kernel, the following vulnerability has been resolved:
rxrpc: Fix the reception of a reply packet before data transmission
Fix rxrpc_receiving_reply() to handle the reception of an apparent reply
DATA packet before rxrpc has had a chance to send any request DATA packets
on a client call by checking to see if the call has been exposed yet by
sending the first packet.
Without this, rxrpc_rotate_tx_window() might oops.
Also fix rxrpc_rotate_tx_window() to handle the Tx queue being empty by
changing the do...while loop into a while loop, just in case a call is
abnormally terminated by an early reply before the last request packet is
transmitted. |

| In the Linux kernel, the following vulnerability has been resolved:
rxrpc: Fix leak of released call in recvmsg(MSG_PEEK)
Fix rxrpc_recvmsg() to also drop the ref it holds on an already-released
call if MSG_PEEK is in force (the function holds a ref on the call
irrespective of whether MSG_PEEK is specified or not). |
| In the Linux kernel, the following vulnerability has been resolved:
crypto: sun4i-ss - Remove insecure and unused rng_alg
Remove sun4i_ss_rng, as it is insecure and unused:
- It has multiple vulnerabilities. sun4i_ss_prng_seed() is missing
locking and has a buffer overflow. sun4i_ss_prng_generate() fails to
fill the entire buffer with cryptographic random bytes, because it
rounds the destination length down and also doesn't actually wait for
the hardware to be ready before pulling bytes from it.
- No user of this code is known. It's usable only theoretically via the
"rng" algorithm type of AF_ALG. But userspace actually just uses the
actual Linux RNG (/dev/random etc) instead. And rng_algs don't
contribute entropy to the actual Linux RNG either. (This may have
been confused with hwrng, which does contribute entropy.)
The sun4i_ss_prng_seed() buffer overflow was reported by Tianchu Chen
and discovered by Atuin - Automated Vulnerability Discovery Engine
There's no point in fixing all these vulnerabilities individually when
this is unused code, so let's just remove it. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: typec: ucsi: Fix race condition and ordering in port unregistration
A synchronization issue exists during port unregistration where pending
partner work items can race against workqueue destruction, leading to
use-after-free conditions:
cros_ec_ucsi cros_ec_ucsi.3.auto: error -ETIMEDOUT: PPM init failed
BUG: kernel NULL pointer dereference, address: 0000000000000000
RIP: 0010:__queue_work+0x83/0x4a0
Call Trace:

sched_clock_cpu+0xc/0x110
irq_exit_rcu+0x18d/0x330
fred_sysvec_apic_timer_interrupt+0x5e/0x80
Fix this by ensuring strict ordering and proper serialization during
teardown:
1. Move ucsi_unregister_partner() to the beginning of the teardown
sequence and protect it under the connector mutex lock.
2. Ensure all pending partner tasks are explicitly flushed and finished
before the workqueue is destroyed.
3. Switch from mod_delayed_work() to a cancel_delayed_work() and
queue_delayed_work() sequence. This guarantees that items currently marked
as pending won't be scheduled an additional time, preventing a double
release of resources which leads to the following crash:
Oops: general protection fault, probably for non-canonical address

To ensure these rules are applied identically across both the normal
teardown and the ucsi_init() error paths, consolidate the cleanup logic
into a new helper, ucsi_unregister_port(). |
| In the Linux kernel, the following vulnerability has been resolved:
drm/vmwgfx: avoid destroy_workqueue(NULL) on vkms init failure
Two paths through vmw_vkms_init() can leave vmw->crc_workq NULL while
still leaving the rest of the driver in a state that calls
vmw_vkms_cleanup() at module unload:
1. vmw_host_get_guestinfo(GUESTINFO_VBLANK, ...) failing or
returning an oversized buffer -- the common case on hosts
without a VBLANK guestinfo entry -- early-returned before the
workqueue allocation.
2. alloc_ordered_workqueue() returning NULL on memory pressure.
vmw_vkms_cleanup() then calls destroy_workqueue(NULL), which
dereferences wq->name and panics.
Fix the first case by removing the early return: vmw->vkms_enabled
is already false on the rpci-failure path so no work will ever be
queued, and allocating the workqueue unconditionally keeps the
control flow simple. Fix the second case by guarding the cleanup
with a NULL check, since alloc_ordered_workqueue() can still fail
under low memory. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/vmwgfx: validate DRAW_PRIMITIVES header size before division
vmw_cmd_draw() computes
maxnum = (header->size - sizeof(cmd->body)) / sizeof(*decl);
where header->size is u32 and is taken straight from the user-supplied
command stream. When header->size is less than sizeof(cmd->body) the
unsigned subtraction wraps to nearly 4 GiB, producing a huge maxnum.
Any user-controlled cmd->body.numVertexDecls then passes the bound and
the loop dereferences decl[i] far past the end of the kernel command
bounce buffer, producing an out-of-bounds read of kernel memory.
Reject undersized headers up front. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/vmwgfx: reject DX_BIND_QUERY without a DX context
vmw_cmd_dx_bind_query() unconditionally dereferences
sw_context->dx_ctx_node->ctx. Userspace can trigger a NULL pointer
dereference from any render-node fd by submitting an execbuf with
dx_context_handle == SVGA3D_INVALID_ID and a SVGA_3D_CMD_DX_BIND_QUERY
opcode in the command stream: dx_ctx_node is left NULL and the kernel
oopses on the assignment. The same NULL is then re-read in
vmw_resources_reserve() via vmw_context_get_dx_query_mob().
All sibling DX handlers fail-close on a missing dx_ctx_node using
VMW_GET_CTX_NODE(). Use the same pattern here, returning -EINVAL up
front before any relocation state is published. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/panthor: validate firmware interface structure sizes
iface_fw_to_cpu_addr() only checks that the firmware-provided MCU virtual
address points inside the shared section. The returned pointer is later
used as a full firmware interface structure, so accepting an address near
the end of the shared section can still lead to out-of-bounds accesses.
Pass the expected object size to iface_fw_to_cpu_addr() and reject ranges
that do not fit entirely in the shared section. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/panthor: reject firmware sections with oversized data
In panthor_fw_load_section_entry(), the data size to copy is calculated
without validating it against the allocated section_size:
section->data.size = hdr.data.end - hdr.data.start;
If a crafted firmware sets data.size larger than the allocated memory,
this could cause a heap buffer overflow in panthor_fw_init_section_mem()
memcpy(section->mem->kmap, section->data.buf, section->data.size);
Additionally, if the section->data.size exceeds the BO size, could this
memset underflow the size calculation, leading to a massive out-of-bounds
zeroing of kernel memory?
memset(section->mem->kmap + section->data.size, 0,
panthor_kernel_bo_size(section->mem) - section->data.size);
Reject section entries whose initial data is larger than the section size. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/vc4: Zero the tile state data array before each BIN job
The binner BO is a single 16MB buffer split into 512KB slots that are
handed out to jobs at submission time and recycled as jobs complete,
without ever being cleared. Each slot holds the job's Tile State Data
Array (TSDA) at its start, followed by the tile allocation pool.
While the tile allocation pool is only walked by the render thread
through branches the binner generated during the current job, the
TSDA is the PTB's own per-tile bookkeeping and is consumed by the
hardware itself. Although the kernel sets the "Auto-initialise Tile
State Data Array" flag in the tile binning mode configuration, the
PTB demonstrably still acts on stale tile state left by the slot's
previous user: the binner ends up creating invalid command streams
with invalid primitive streams and branches, which can cause GPU hangs
as observed in [1][2].
Zero the TSDA when the job's binning slot is configured. This clears
48 bytes per tile (~24KB for a 1080p frame) in the submission path, and
guarantees the PTB never sees another job's tile state.
The tile count is only checked for being non-zero today, so the 8-bit
fields it comes from can describe a tile state array almost six times
larger than the slot it has to live in. Bound it before the slot is
handed out, since such size decides how much of the slot is left for
the tile alloc pool. |
| @fastify/multipart is a multipart form-data parser for Fastify. In versions from 3.0.0 up to but not including 10.1.1, request.saveRequestFiles() can leave completed temporary files on disk when a client disconnects while the parser is advancing between multipart parts. The iterator rejection that occurs between parts falls outside the per-file cleanup path, so an earlier completed file is never removed. An unauthenticated client can repeat this to cause persistent, linear disk consumption, leading to denial of service. This is an incomplete-fix variant of CVE-2025-24033. The issue is fixed in @fastify/multipart 10.1.1. Users should upgrade to 10.1.1. |
