| Integer Overflow to Buffer Overflow vulnerability in Samsung Open Source rlottie allows Overflow Buffers. |
| MKVToolNix through 101.0 contains a heap buffer overflow in the bundled avilib library's ODML superindex parser due to integer wraparound in 32-bit arithmetic. Attackers can craft a malicious AVI file with oversized entry counts that cause an undersized heap allocation, allowing a heap buffer overflow when the file is parsed with mkvmerge. |
| NVIDIA GPU Display Driver for Windows and Linux contains a vulnerability in the kernel mode layer, where a user could cause an incorrect conversion between numeric types. A successful exploit of this vulnerability might lead to code execution, denial of service, escalation of privileges, information disclosure, and data tampering. |
| NVIDIA vGPU Virtual GPU Manager for Linux contains a vulnerability in the kernel mode layer where an attacker could cause an incorrect numeric conversion. A successful exploit of this vulnerability might lead to code execution, denial of service, escalation of privileges, information disclosure, and data tampering. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: zero extend the result of an arena 32-bit cmpxchg
bpf_convert_ctx_accesses() rewrites an atomic on an arena pointer from
BPF_STX | BPF_ATOMIC to BPF_STX | BPF_PROBE_ATOMIC, and it runs before
bpf_opt_subreg_zext_lo32_rnd_hi32().
That pass emits an explicit zero extension for a 32-bit cmpxchg even
when bpf_jit_needs_zext() is false. This is done because on some
architectures 32-bit cmpxchg requires explicit zero extension for the
dst register. E.g. on x86-64 'lock cmpxchg' does not change the %eax
if comparison is successful, while BPF semantics declare that each
operation on a 32-bit register zero extends it's upper half.
is_cmpxchg_insn() matches BPF_MODE == BPF_ATOMIC only, so an arena
cmpxchg misses said zero extension adjustment. This patch adjusts
is_cmpxchg_insn() to match BPF_PROBE_ATOMIC alongside BPF_ATOMIC. |
| In the Linux kernel, the following vulnerability has been resolved:
EDAC/device_sysfs: Use kstrtouint() for poll_msec to prevent truncation
The poll_msec sysfs store file uses simple_strtoul() which accepts an unsigned
long, but the target field (poll_msec) is unsigned int. On 64-bit systems,
a value > UINT_MAX is silently truncated when stored.
Fix the mismatch by using kstrtouint() instead. This rejects values larger
than UINT_MAX at parse time, making truncation impossible. Also add a check
for value < 1 to reject the 0-delay case, which would cause the poll work to
spin without delay and consume 100% CPU. |
| Incorrect conversion between numeric types in Microsoft JScript allows an unauthorized attacker to execute code over a network. |
| LibRaw 0.22.0 contains an incorrect numeric conversion vulnerability in LibRaw::parse_tiff_ifd() when processing TIFF tag 0x00fe (NewSubfileType). A specially crafted RAW, TIFF, or DNG file can supply an attacker-controlled NewSubfileType value outside the range of a signed int. The parser converts this value and narrows it to int without performing range validation. This out-of-range conversion triggers undefined behavior, resulting in process termination and denial of service. |
| In the Linux kernel, the following vulnerability has been resolved:
cifs: validate idmap key payload length
The cifs.idmap key type stores its payload length in key->datalen, which
is limited to U16_MAX. Accepting a larger key payload truncates the
recorded length and can make later users interpret the payload using
inconsistent bounds.
Reject oversized preparsed payloads before allocating or copying them.
This keeps key->datalen consistent with the stored data for both inline
and separately allocated idmap payloads. |
| In the Linux kernel, the following vulnerability has been resolved:
ACPICA: Fix integer overflow in acpi_ex_opcode_3A_1T_1R() (mid_op)
Add overflow check for Index + Length to prevent integer overflow
when calculating the truncation length. This prevents negative
size parameter being passed to memcpy(). |
| NanoSVG 239e102ec contains an incorrect numeric conversion vulnerability in nsvg__curveDivs() during SVG stroke rasterization. A specially crafted SVG document containing an extremely large stroke-width can cause floating-point rounding to produce a zero subdivision angle. The subsequent arc division yields infinity, which is converted to int without range validation, resulting in undefined behavior and process termination, leading to denial of service. |
| MuJS e892c9fdb contains an incorrect numeric conversion vulnerability in jsR_isindex() in jsrun.c. A specially crafted JavaScript input containing an excessively large numeric array index can cause an out-of-range floating-point value to be converted to an integer without proper range validation. This results in undefined behavior and can cause process termination, leading to denial of service. |
| NanoSVG commit 239e102ec contains an incorrect numeric conversion vulnerability in the rasterizer's nsvg__addActive() function. A specially crafted SVG document containing sufficiently large geometry coordinates can cause fixed-point-scaled edge coordinates to exceed the range representable by int. The rasterizer subsequently converts these values to int without range validation, resulting in undefined behavior and possible process termination, leading to denial of service. |
| In the Linux kernel, the following vulnerability has been resolved:
octeontx2-pf: reset HTB scheduler topology before freeing queues
HTB offload programs NIX_AF_TLxX_TOPOLOGY on QoS-allocated scheduler
queues via otx2_qos_txschq_set_parent_topology(), but teardown freed
those queues without clearing TOPOLOGY. The AF only restores PARENT and
SCHEDULE on free, so PRIO_ANCHOR/RR_PRIO settings can survive in the
shared scheduler pool and affect later allocations.
Add otx2_qos_reset_schq_topology() and otx2_qos_free_hw_schq() to zero
TL4 through TL2 TOPOLOGY before each schq is returned to the AF during
hierarchy teardown and cfg rollback. Skip the aggregation level (TL1):
it is a per-tx-link queue shared by the PF, default Tx hierarchy and VFs,
and is not freed back to the AF by nix_txschq_free_one(). |
| In the Linux kernel, the following vulnerability has been resolved:
ACPICA: add boundary checks in acpi_ps_get_next_field()
Add boundary checks in acpi_ps_get_next_field() to prevent out-of-bounds
access. |
| In the Linux kernel, the following vulnerability has been resolved:
media: v4l2-ctrls: validate AV1 tile counts
The stateless AV1 decoders use tile_info.tile_cols and tile_rows as loop
bounds and as indices into the mi_*_starts[] and *_in_sbs_minus_1[]
arrays, as the divisor for context_update_tile_id, and their product
bounds the per-tile descriptor buffers, but std_validate_compound() does
not bound these u8 fields. Reject a V4L2_CTRL_TYPE_AV1_FRAME whose
tile_cols or tile_rows exceeds V4L2_AV1_MAX_TILE_COLS / _ROWS, or whose
product exceeds V4L2_AV1_MAX_TILE_COUNT. A zero tile count is left to the
consuming driver so the zero-initialised control that existing userspace
submits is still accepted. |
| In the Linux kernel, the following vulnerability has been resolved:
vdpa_sim_net: check TX pull result before RX copy
vringh_iov_pull_iotlb() returns a signed byte count. A failed TX pull is
currently added to the unsigned byte counter and then passed as a size_t
length to receive_filter() and vringh_iov_push_iotlb(). A negative error
can therefore become a large length in the RX path.
Handle non-positive pull results before every length use. Count the TX
error and complete the consumed TX descriptor with zero bytes.
I found this bug myself, though the patch was written with AI assistance. |
| In the Linux kernel, the following vulnerability has been resolved:
xfs: fix unit conversions in per_binval computation
LOLLM noticed that we're doing the unit conversion in the per_binval
computation backwards -- xfs_buf_inval_log_space's second parameter is
supposed to be in bytes, but max_binval is in units of fsblocks. Hence
the conversion should be FSB -> B, not the other way around. |
| In the Linux kernel, the following vulnerability has been resolved:
mptcp: pm: kernel: drop pending ADD_ADDR when removing ID0
The in-kernel MPTCP path manager can leave a stale ADD_ADDR announcement
entry alive when removing the id 0 endpoint. This happens because the id 0
removal path does not tear down pending announcements, unlike the non-zero
id path.
When the PM later reselects id 0 after adding another signal endpoint, it
finds the stale anno_list entry and hits WARN_ON_ONCE(mptcp_pm_is_kernel())
in mptcp_pm_announced_alloc().
Root cause: asymmetry between removal paths.
- Non-zero id path: mptcp_nl_remove_subflow_and_signal_addr() calls
mptcp_pm_remove_announced() to clean up.
- Id 0 path: mptcp_nl_remove_id_zero_address() skips cleanup entirely.
Fix by making the id 0 path symmetric: call mptcp_pm_announced_remove()
and decrement add_addr_signaled before queuing the RM_ADDR.
Subtle detail: signal endpoints are stored in anno_list with port 0, but
msk_local carries the connection's local port. In other words, entries
linked to ID0 paths should have port == 0. A follow-up patch will ensure
that. mptcp_pm_announced_remove() uses use_port=true for comparison. So
clear the port before the lookup. |
| In the Linux kernel, the following vulnerability has been resolved:
bnxt_en: Propagate TPA buffer allocation failures in bnxt_queue_mem_alloc()
bnxt_alloc_one_tpa_info_data() returns -ENOMEM as soon as one allocation
fails. This leaves the remaining rxr->rx_tpa[] entries zeroed.
bnxt_queue_mem_alloc() discards that return value, so the partially
initialized ring is installed by bnxt_queue_start().
Since the agg_id is picked by the hardware and bnxt_alloc_agg_idx maps
it to a SW index in rxr->rx_tpa[], it is possible that an uninitialized
slot can be chosen which would hand a zero DMA address to the device.
Fix this by checking the return value of bnxt_alloc_one_tpa_info_data
and unwinding, freeing the ring buffers. |
