| In Qt for MCUs, a Text element that displays styled text halts the device if an <img> tag in the text contains an attribute with an empty value. The text parser passes the empty value to an internal check that only accepts non-empty values. The check fails and reports an error, and the default error handler halts the device. |
| A flaw was found in ModemManager. When parsing a Cell Broadcast Message, some 3GPP data-coding-scheme values (8-bit and reserved character sets) are not handled. The process hits a reachable assertion and aborts. An attacker who can deliver a crafted Cell Broadcast PDU over the radio network, or via a modem AT channel, can cause ModemManager to exit. Repeated aborts can exhaust systemd's default start limit and leave the service failed. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Reject non-scalar bpf_loop iteration counts
bpf_loop() declares its nr_loops argument as ARG_ANYTHING. Privileged
programs may pass pointer values to such arguments, so check_func_arg()
lets a pointer-valued R1 reach the helper-specific checks.
Since commit bb124da69c47 ("bpf: keep track of max number of bpf_loop
callback iterations"), the verifier marks R1 precise and reads its upper
bound to limit callback simulation. Precision backtracking only accepts
scalar registers, so passing a pointer instead triggers the "backtracking
misuse" verifier warning. Kernels with panic_on_warn enabled subsequently
panic.
Introduce ARG_SCALAR for helper arguments that only accept scalar values
and use it for bpf_loop() nr_loops. Generic helper argument validation then
rejects pointers before loop inlining and precision processing. |

This is a consequence of commit 0fe77e57588b98, which added the
following assertion to xfs_da_grow_inode_int:
ASSERT(args->total >= dp->i_nblocks - nblks);
Tracing this back to xrep_dir_swap_prep, I noticed that the xfs_da_args
object that's passed to xfs_dir2_sf_to_block sets args->total to 1.
This is incorrect because mkfs set the directory block size to 8k and
the filesystem block size to 4k. In other words, args->total should be
2 here, not 1.
Dave Chinner tripped over the same problem with the same branch through
a different channel -- his test setup set the fs block size to 1k, in
which case the directory block size is still set to 4k. Here,
args->total should be 4.
Changing the assignment of args->total to sc->mp->m_dir_geo->fsbcount
makes the assertion go away, but that isn't a complete fix. In
xrep_tempexch_estimate, we also incorrectly assume that a shortform
conversion requires 1 fsblock when it should be m_dir_geo->fsbcount.
Without that, we can under-reserve space in the transaction and cause a
filesystem shutdown.
Note that the xfs_dabuf_nfsb helper will compute the correct value for
directories and xattr, so we use that instead of open-coding the logic.
Also fix xrep_xattr_swap_prep to assign args->total via xfs_dabuf_nfsb
to avoid one logic bomb if we ever support multi-fsblock attrs.

| In the Linux kernel, the following vulnerability has been resolved:
perf/ftrace: Fix WARNING in __unregister_ftrace_function
perf_ftrace_function_unregister() unconditionally calls
unregister_ftrace_function() without checking whether the ftrace_ops
was ever successfully registered. This triggers a WARN_ON in
__unregister_ftrace_function() when the ops doesn't have
FTRACE_OPS_FL_ENABLED set.
This can happen during perf_event_alloc() error cleanup when
perf_trace_destroy() is called via __free_event() on an event whose
ftrace_ops registration failed or was already torn down by
perf_try_init_event()'s err_destroy path.
The call path is:
perf_event_alloc() error cleanup
-> __free_event()
-> event->destroy() [tp_perf_event_destroy]
-> perf_trace_destroy()
-> perf_trace_event_close()
-> TRACE_REG_PERF_CLOSE
-> perf_ftrace_function_unregister()
-> unregister_ftrace_function()
-> __unregister_ftrace_function()
-> WARN_ON(!(ops->flags & FTRACE_OPS_FL_ENABLED))
Fix this by checking FTRACE_OPS_FL_ENABLED before attempting to
unregister. If the ops is not enabled, just free the filter and
return success. |

ext4: fix transaction overflow during writeback
Commit 95ad8ee45cdb ("ext4: correct the reserved credits for extent
conversion") was correct to note that we need to reserve enough credits
for all extents possibly underlying a large folio. However it was too
eager to reduce the number of reserved credits. Extent conversion may
not only need to touch several leaf extent blocks, it may also need to
split extents - for example a single large unwritten extent may need to
be split into many small written ones in case of sparse folio dirtying.
This can thus result not only in extent leaf modifications but also in a
need to allocate new extent tree nodes. As a result the reserved
transaction credits were not sufficient in some corner cases. Use
ext4_meta_trans_blocks() for correct upper bound credit estimate. |
| vLLM before 0.29.0 accepts user-controlled stop_token_ids on the OpenAI-compatible POST /v1/completions and POST /v1/chat/completions endpoints but validates only that the values are integers, not that each token id is within the model vocabulary/logits range. When min_tokens > 0, the stop token ids are used as logits indices to suppress stop tokens, so an out-of-range id reaches a CUDA indexing operation (index_put_) and triggers a device-side assertion. An authenticated API user can send a single malformed completion request that returns 500 Internal Server Error and puts EngineCore into a fatal state, causing subsequent requests to fail until the service is restarted (denial of service). |
| During query planning when reading the sort pattern in raw BSONObj form, in some places we don’t explicitly handle the meta expression case. This may lead to incorrect transformations leading to invariant failure. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Reject tail calls directly from callback frames
A tail call from a non-zero frame is modeled as a return from that frame.
The verifier makes R0 unknown and calls prepare_func_exit() for the taken
branch.
When the current frame is a synchronous callback, prepare_func_exit()
enforces the callback return-value contract and marks R0 precise. Since the
tail-call path synthesized R0 rather than deriving it from an instruction,
precision backtracking reaches the callback-calling instruction with R0
still requested and triggers the "callback unexpected regs" verifier bug.
A CAP_BPF task can therefore cause a WARN and an -EFAULT BPF_PROG_LOAD.
Tail calls reachable from callbacks are already rejected later by
check_max_stack_depth(). Reject a tail call made directly by a callback
before constructing the inconsistent return state, using the existing
diagnostic. Tail calls from ordinary subprograms keep their current
behavior. |
| In the Linux kernel, the following vulnerability has been resolved:
net: ethernet: oa_tc6: Improve the error recovery
When oversubscribed traffic causes lot of buffer overflow errors,
probably due to loss of data chunks, driver fails to find a
data chunk with end_valid bit set, before it runs out of sk buffer
space. As a result, assert is seen during skb_put.
Now, check is made if skb buffer has enough tailroom for the
incoming data before accepting. If there is no room, current
frame is abandoned and it will start looking for a data chunk
with start_valid bit, that is a new frame.
SK buffer allocation error is considered as recoverable error.
rx_buf_overflow flag is too specific and no longer the only
condition this flag is used for. Therefore it is renamed as
wait_until_start_valid. This is more appropriate as this flag
is used to look for the next data chunk with SV bit set, after
failures like buffer overflow, buffer allocation failure, skb pointer
validity besides buffer overflow error.
Not writing to status0 if it reads 0. |
| Creating a "2dsphere_bucket" index on a non-timeseries bucket collection will succeed, but any subsequent attempt to insert a document which triggers updating that index will crash the server. A similar issue occurs when creating "queryable_encrypted_range" indices.
This issue affects MongoDB Server v7.0 versions prior to 7.0.32, v8.0 versions prior to 8.0.21 and v8.2 versions prior to 8.2.6 |
| A reachable assertion vulnerability exists in YARA 4.5.8 when loading crafted .yrc compiled rule files. An attacker can provide a malicious file with an invalid arena configuration (num_buffers=0) that triggers an assertion failure in yr_arena_get_ptr(), causing the application to terminate. |
| vLLM through 0.29.0 contains a denial of service vulnerability in the NIXL connector's prefix caching implementation that fails to properly validate block counts across multi-prompt completion requests in prefill/decode disaggregated deployments. Attackers can trigger an assertion failure in NixlBaseConnectorWorker._apply_prefix_caching by submitting completion requests with multiple prompts of varying lengths, causing the decode worker to terminate and become unavailable until restarted. |
