CVSS v3.1 |
| vLLM is an inference and serving engine for large language models. From 0.19.0 until 0.32.0, authenticated callers can supply a request chat template when no server-side --chat-template is configured, or a malicious model repository can provide a template that is compiled and rendered by tokenizer.apply_chat_template() without a wall-clock timeout, output-size limit, or iteration bound. Rendering runs in a ThreadPoolExecutor with one worker by default, so a nonterminating render can block /v1/responses and other chat-template users after the request ends, while an output-expanding render can exhaust server memory. Harmony models are not affected because they do not use this Jinja path. This issue is fixed in version 0.32.0. |
| zip is a zip library for Rust that supports reading and writing simple ZIP files. From 5.1.0 until 9.0.0, applications built with the legacy-zip feature can reserve output capacity from an attacker-controlled ZIP64 uncompressed size before validating the compressed stream. The ShrinkDecoder path in src/legacy/shrink.rs can panic with a capacity overflow during ZipArchive::extract, and the Reduce and Implode decoders contain the same unbounded preallocation pattern. An unhandled panic can terminate an archive-processing service. This issue is fixed in version 9.0.0. |
| Twisted is an event-based framework for internet applications, supporting Python 3.6+. Prior to 26.10.0rc1, twisted.words.protocols.irc.IRC.dataReceived retains all bytes received without a line feed in its per-connection buffer and applies no maximum line length. The twisted.words.service.IRCUser server subclass inherits this behavior, and buffering occurs before PASS, NICK, or USER authentication commands. An unauthenticated connection can continuously grow the buffer until the shared server process runs out of memory and drops all users. This issue is fixed in version 26.10.0rc1. |
| toml-node is a TOML parser for Node.js and the browser. Prior to 5.0.1, toml.parse() passes unbounded hexadecimal, octal, binary, and decimal digit sequences from lib/parser.js to BigInt() before reduceInteger() in lib/compiler.js checks whether the resulting value fits the TOML 64-bit integer range. Converting a sufficiently long integer string consumes super-linear CPU time and synchronously blocks the Node.js event loop, allowing one attacker-supplied TOML document to deny service to concurrent work in the process. The later range check cannot prevent the conversion cost because it executes after BigInt(). This issue is fixed in version 5.0.1. |
| In the Linux kernel, the following vulnerability has been resolved:
accel/amdxdna: Fix mm_struct reference leak in aie2_populate_range()
aie2_populate_range() jumps back to the again label without calling
mmput(mm), leaking a reference to the mm_struct.
Add the missing mmput() before jumping to again. |
| In the Linux kernel, the following vulnerability has been resolved:
mm/migrate_device: fix pgtable leak in migrate_vma_insert_huge_pmd_page
When migrate_vma_insert_huge_pmd_page() jumps to unlock_abort due
to a PMD check failure, the pgtable allocated earlier via
pte_alloc_one() is never freed, causing a memory leak.
Added free_abort label to release the pgtable in error path. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: buffer: Fix DMA fence leak in iio_buffer_enqueue_dmabuf()
iio_buffer_enqueue_dmabuf() allocates a struct iio_dma_fence (104 bytes,
kmalloc-128) via kmalloc_obj()+dma_fence_init(), which sets the initial
kref to 1. It then calls dma_resv_add_fence() which takes a second
reference (kref=2), and stores a raw pointer in block->fence.
On the success path the function returns without calling dma_fence_put()
to release the initial reference, so every buffer enqueue permanently
leaks one kmalloc-128 allocation.
The iio_buffer_cleanup() work item only releases the temporary reference
taken during completion signalling by iio_buffer_signal_dmabuf_done();
the initial reference from dma_fence_init() is never released.
With four iio_rwdev instances at 240kHz and 512 samples per buffer,
this produces ~1875 kmalloc-128 allocations per second matching the
observed slab growth exactly. A test with ftrace confirmed that the
dma_fence_destroy event was never triggered.
Fix by calling dma_fence_put() after dma_resv_add_fence(), transferring
ownership of the fence to the DMA reservation object. The DMA fence then
gets properly discarded after being signalled. |
| Apache bRPC versions before 1.18.0 do not consistently enforce the configured max_body_size limit in non-progressive HTTP/1 and HTTP/2 parsing and in memcache and couchbase response parsing.
A remote unauthenticated peer can cause an affected process to buffer message data beyond the configured limit, which may lead to memory exhaustion and denial of service.
Users should upgrade to 1.18.0 or apply the patch from PR https://github.com/apache/brpc/pull/3382 . The fix rejects oversized buffered HTTP bodies, returns HTTP 413 for HTTP/1 requests, resets oversized HTTP/2 streams, and rejects oversized memcache and couchbase responses from their declared lengths. Progressive HTTP reading remains supported because it uses bounded buffering. |
| Crypt::Age versions before 0.004 for Perl allow CPU exhaustion via an unbounded number of recipient stanzas, each costing an X25519 scalar multiplication in unwrap_file_key.
The header parser accepts any number of recipient stanzas, and unwrap_file_key tries every identity against every X25519 stanza. Each attempt runs a scalar multiplication, an HKDF and a ChaCha20-Poly1305 open. The header MAC cannot be checked first, because its key comes from the file key, which only a successful unwrap produces.
Each stanza is 98 bytes of attacker-chosen header and buys one scalar multiplication per identity held, and the file is rejected only after every one of them has run. A caller reaches this through decrypt, decrypt_file or decrypt_filehandle whenever it decrypts a file it did not write. |
| In the Linux kernel, the following vulnerability has been resolved:
gpiolib: fix memory leak in gpiod_set_array_value_complex() on error paths
A drive-by review by Sashiko reports that, after a failed call to
gpiochip_set_multiple(), gpiod_set_array_value() returns abruptly,
bypassing the freeing of possibly alloced bitmaps, potentially leaking
memory. It is an unlikely error path, but is possible.
Defer the return code check until after the bitmap_free() block. |
| In the Linux kernel, the following vulnerability has been resolved:
mmc: sdhci-sprd: disable runtime PM on remove
sdhci_sprd_probe() enables runtime PM, while sdhci_sprd_remove() does
not perform the corresponding runtime PM cleanup.
The probe failure path disables runtime PM before disabling the clocks,
but the normal remove path directly disables clocks that are also
managed by the runtime PM callbacks. If the device is runtime
suspended, those clocks may already be disabled.
Resume the device before removal, disable runtime PM and drop the
temporary runtime PM reference before disabling the clocks.
This issue was found by manual code inspection. |
| In the Linux kernel, the following vulnerability has been resolved:
HID: steam: Refactor registration
This refactors and simplifies the registration/unregistration flow. Since
we now only perform registration when the client isn't opened anymore, the
logic for handling that can be removed, and the rest of the function
streamlined.
We also remove the previous assumption that we have a serial number to show
we're registered, replacing it with a single purpose boolean.
In a previous refactor the code for unregistering a battery if later
registration steps failed was accidentally left out. As a result, a
lingering power_supply object could get left over after the steam object
was torn down. This is also fixed here. |
| In the Linux kernel, the following vulnerability has been resolved:
HID: alps: unregister DualPoint Stick input device on remove
alps_input_configured() allocates a second input device ("DualPoint
Stick") with input_allocate_device() and registers it, but the
alps_driver struct has no .remove handler and input2 is not tracked in
hdev->inputs. The default remove path (hid_hw_stop -> hidinput_disconnect)
only iterates hdev->inputs, so input2 is never unregistered and leaks
on every device removal.
Add a .remove handler that stops the device first (preventing URB
callbacks from touching input2 during teardown) and then unregisters
input2. |
| In the Linux kernel, the following vulnerability has been resolved:
ipmr: account multicast table and route memory
A netadmin in a user+net namespace can create many IPv4 and IPv6
multicast routing tables with MRT_TABLE and MRT6_TABLE. Each unseen
id allocates an mr_table via the shared mr_table_alloc(), links it
into the per-net list, and leaves it until netns teardown. Those
objects were not charged to memcg, so the host unreclaimable slab
grows with the table count.
Account mr_table allocations with GFP_KERNEL_ACCOUNT and mark the
IPv4/IPv6 MFC caches SLAB_ACCOUNT. This matches the established
handling of IP addresses, routes and alternate interface names.
Unresolved MFC entries are still allocated from softIRQ with
GFP_ATOMIC and are not charged. They expire after 10 seconds and are
bounded by the socket receive queue; see commit 0079ad8e8dc3
("ipmr: remove hard code cache_resolve_queue_len limit"). |
| 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. |
| In the Linux kernel, the following vulnerability has been resolved:
kasan: fix cache shrink race with CPU hotplug
kasan_quarantine_remove_cache() first invokes per_cpu_remove_cache() on
all online CPUs. Each callback moves objects belonging to the cache from
cpu_quarantine to the CPU's shrink_qlist, where they can later be freed
from task context.
kmem_cache_destroy() invokes the quarantine removal path while holding
cpus_read_lock(), but kmem_cache_shrink() does not. The latter can
therefore race with CPU offlining as follows:
kmem_cache_shrink() CPU hotplug
------------------- -----------
on_each_cpu()
CPU1 moves objects to
CPU1's shrink_qlist
on_each_cpu() returns
CPU1 goes offline
kasan_cpu_offline()
drains cpu_quarantine
leaves shrink_qlist untouched
for_each_online_cpu()
skips CPU1
The objects left on CPU1's shrink_qlist are not returned to the slab
allocator. This may prevent kmem_cache_shrink() from releasing slabs that
would otherwise become empty. If CPU1 remains offline, a later
kmem_cache_destroy() also skips the list and can report that the cache
still contains objects.
An intermittent occurrence was observed with a virtio-9p filesystem. The
mount and umount commands both returned 0, but the kernel logged the
following during the userspace-triggered teardown:
[ 2994.380134][ T111] BUG 9p-fcall-cache-1 (Tainted: G B ): Objects remaining on __kmem_cache_shutdown()

Thus, a successful umount left objects in the 9p fcall cache and prevented
the cache from being destroyed cleanly.
Per-CPU shrink_qlist storage exists for every possible CPU, and each list
is protected by its own raw spinlock. Iterate over possible CPUs so that
a list populated before its CPU went offline is drained as well.
for_each_possible_cpu() can do more work than for_each_online_cpu(), but
this change only affects CONFIG_KASAN_GENERIC kernels. The extra work is
limited to cache shrink and cache destruction paths and does not affect
the normal allocation/free fast path. It adds one raw-spinlock-protected
scan of each possible CPU's shrink list. These lists are normally empty;
a non-empty list is traversed to remove objects belonging to the cache
being shrunk or destroyed. |
| In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scmi: Free transport channel on IDR failure
If transport channel setup succeeds but the following IDR insertion fails,
the error path destroys the transport device and frees the channel info
without invoking the transport cleanup callback.
Call chan_free() before destroying the device so transport specific
resources such as IRQs, mailbox channels and mapped shared memory are
released consistently with the normal teardown path. |
| In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scmi: Drop handle on protocol bind failures
The SCMI bus notifier acquires an SCMI handle when the driver core emits
BUS_NOTIFY_BIND_DRIVER, before invoking the protocol driver probe
callback. The protocol probe path only checks whether sdev->handle is
set.
If device_link_add() fails after the handle has been acquired, the
protocol device can still bind with a valid handle but without the
dependency link to the SCMI parent. A concurrent parent unbind can then
miss the child and tear down the SCMI instance while the child still
holds a handle into it.
If the protocol driver probe later fails, for example with
-EPROBE_DEFER, the driver core emits BUS_NOTIFY_DRIVER_NOT_BOUND rather
than BUS_NOTIFY_UNBOUND_DRIVER. The SCMI notifier only released the
handle on BUS_NOTIFY_UNBOUND_DRIVER, so each failed protocol-device bind
leaked the SCMI instance users refcount and left sdev->handle set after
the failed probe.
Make the link helper report failure and drop the acquired handle if the
link cannot be created. Also handle BUS_NOTIFY_DRIVER_NOT_BOUND in the
same cleanup path used for unbind so failed probes balance the earlier
BUS_NOTIFY_BIND_DRIVER acquisition. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/erdma: complete object teardown when the destroy command fails
erdma_destroy_qp(), erdma_destroy_cq(), erdma_dereg_mr(), and
erdma_destroy_ah() returned early when erdma_post_cmd_wait() failed,
leaking the queue buffers, MTTs, doorbells and the STAG, QPN, CQN and AHN
identifiers. A command timeout clears ERDMA_CMDQ_STATE_OK_BIT and
permanently disables the command queue, so no retry can succeed; the RDMA
core keeps the object after a failed destructor and forced uverbs cleanup
then nulls the pointers, making the resources unreachable.
Warn on failure but release every software-owned resource and return
success, since during terminal destruction the hardware command result is
only diagnostic. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/cxgb4: Fix dereg_skb leak and double free in write_tpt_entry()
When the device is in the fatal error state, write_tpt_entry() returns -EIO
before handing the caller's preallocated skb to the transmit path; its
allocation-failure returns do the same. c4iw_dereg_mr() ignores the error
and frees mhp, leaking mhp->dereg_skb. c4iw_get_dma_mr() instead frees the
skb a second time after dereg_mem() already consumed it, a double free.
Make write_tpt_entry() the sole owner of a non-NULL skb, freeing it on
every return preceding handoff to c4iw_ofld_send(): fatal error, tpt and
stag allocation failure. c4iw_ofld_send() consumes the skb on success and
error alike, so drop the redundant kfree_skb() in c4iw_get_dma_mr() after
dereg_mem(). |
