| Blender before 4.5.15 and 5.x before 5.2.3 contains a heap buffer overflow vulnerability in the blend file thumbnail extractor caused by 32-bit integer overflow in thumb_data_vertical_flip(). Attackers can craft a .blend file with malicious TEST block dimensions that trigger an out-of-bounds write when blender-thumbnailer or the Windows shell extension previews it, causing crashes or code execution. |
| NocoDB before 2026.08.0 contains a clickjacking vulnerability that allows any origin to frame the authenticated interface because no X-Frame-Options or CSP frame-ancestors headers are sent. Attackers can overlay a signed-in user's session from a malicious page, tricking clicks that modify or delete records, change sharing settings, or invite collaborators. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: check num_entries in GEM_OP GET_MAPPING_INFO
kvcalloc(args->num_entries, sizeof(*vm_entries), GFP_KERNEL) at
amdgpu_gem.c:1050 uses the user-supplied num_entries directly without
any upper bounds check. Since num_entries is a __u32 and
sizeof(drm_amdgpu_gem_vm_entry) is 32 bytes, a large num_entries
produces an allocation exceeding INT_MAX, triggering
WARNING in __kvmalloc_node_noprof(), causing a kernel WARNING,
TAINT_WARN, and panic on CONFIG_PANIC_ON_WARN=y systems.
Add a size bounds check before we invoke the kvzalloc() to
reject oversized num_entries early with -EINVAL.

| Starlet versions from 0.20 before 0.33 for Perl allow CPU exhaustion via regular expression backtracking when decoding chunked request bodies.
A chunk-size line is matched as a run of hex digits, then .* and a CRLF. A run followed by a bare LF and then a CRLF can never match, and the engine retries the match once for each digit, so the time taken grows with the square of the run length. Nothing limits the length of the run, which can span several reads.
A remote attacker can occupy a worker for about a minute of CPU time with one 128 KiB request, before the application is called. |
| In the Linux kernel, the following vulnerability has been resolved:
USB: serial: mct_u232: fix memory corruption with small endpoint
The driver overrides the maximum transfer size for a specific device
which only accepts 16 byte packets for its 32 byte bulk-out endpoint.
Make sure to never increase the maximum transfer size to prevent slab
corruption should a malicious device report a smaller endpoint max
packet size than expected. |
| In the Linux kernel, the following vulnerability has been resolved:
USB: serial: mxuport: fix memory corruption with small endpoint
Make sure that the bulk-out endpoint max packet size is at least eight
bytes to avoid user-controlled slab corruption should a malicious device
report a smaller size. |
| In the Linux kernel, the following vulnerability has been resolved:
USB: serial: cypress_m8: validate interrupt packet headers
cypress_read_int_callback() parses the interrupt-in buffer according to
the selected Cypress packet format. Format 1 has a two-byte status/count
header and format 2 has a one-byte combined status/count header. The
usb-serial core sizes the interrupt-in buffer from the endpoint
descriptor's wMaxPacketSize, and successful interrupt transfers can
complete short when URB_SHORT_NOT_OK is not set.
Check that the completed packet contains the selected header before
reading it. Malformed short reports are ignored and the interrupt URB is
resubmitted through the existing retry path, preventing out-of-bounds
header-byte reads.

| In the Linux kernel, the following vulnerability has been resolved:
USB: serial: belkin_sa: validate interrupt status length
The Belkin interrupt callback treats interrupt data as a four-byte
status report and reads LSR/MSR fields at offsets 2 and 3. The
interrupt-in buffer length is derived from endpoint wMaxPacketSize, and
short interrupt transfers may complete successfully with a smaller
actual_length.
Check the completed interrupt packet length before parsing status
fields so short interrupt endpoints and short successful packets are
ignored instead of causing out-of-bounds or stale status-byte reads.

| In the Linux kernel, the following vulnerability has been resolved:
usb: usbtmc: check URB actual_length for interrupt-IN notifications
USBTMC devices can use an optional interrupt endpoint for notification
messages. These typically contain two-byte headers indicating the
payload format, but the driver does not check if these headers are
present before accessing the data buffers. In cases where the URB
actual_length is not enough to fit these headers, the driver will either
cause an out-of-bounds read, or consume stale leftover data from a
previous notification.
Fix by checking if actual_data contains enough bytes for the headers,
otherwise resubmit URB to the interrupt endpoint. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: typec: tcpm/tcpci_maxim: validate header NDO against RX_BYTE_CNT
A broken/malicious port can transmit a CRC-valid frame whose header
advertises up to seven data objects but whose body carries fewer than
that. Check for this, and rightfully reject the message, instead of
reading from uninitialized stack memory. |
| In the Linux kernel, the following vulnerability has been resolved:
USB: serial: safe_serial: fix memory corruption with small endpoint
Make sure that the bulk-out buffer size is at least eight bytes to avoid
user-controlled slab corruption in "safe" mode should a malicious device
report a smaller size. |
| In the Linux kernel, the following vulnerability has been resolved:
uio: uio_pci_generic_sva: fix double free of devm_kzalloc() memory
uio_pci_sva allocates struct uio_pci_sva_dev with devm_kzalloc() in
probe(), but then calls kfree(udev) both on the probe() error path
(label out_free) and again in remove().
Because devm_kzalloc() allocations are devres-managed and are freed
automatically when the device is detached (including after a failing
probe() and during driver unbind), the explicit kfree() can lead to a
double free.
If probe() fails after devm_kzalloc(), the error path frees udev and
devres cleanup will free it again when the core unwinds the partially
bound device. On normal driver removal, remove() frees udev and devres
will free it again when the device is detached.
This issue was identified by a static analysis tool I developed and
confirmed by manual review. Fix by removing the manual kfree() calls
and dropping the now-unused label. |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: OOB read regression in smb_check_perm_dacl() ACE-walk loops
Commit d07b26f39246 ("ksmbd: require minimum ACE size in
smb_check_perm_dacl()") introduced a transposed bounds check:
if (offsetof(struct smb_ace, sid) + aces_size < CIFS_SID_BASE_SIZE)
Since offsetof(..sid) is 8 and CIFS_SID_BASE_SIZE is 8, this evaluates
to `aces_size < 0`. Because `aces_size` is always non-negative, this
check becomes dead code and never breaks the loop.
Worse, that commit removed the old 4-byte guard, meaning the loop now
reads `ace->size` (offset 2) even when `aces_size` is 0-3 bytes. This
re-opens a 2-byte heap out-of-bounds (OOB) read past the pntsd allocation
during subsequent SMB2_CREATE operations.
Fix this by properly transposing the comparison to require at least
16 bytes (8-byte offset + 8-byte SID base), matching the correct form
used in smb_inherit_dacl(). |
| In the Linux kernel, the following vulnerability has been resolved:
xfrm: iptfs: reset runtime state when cloning SAs
iptfs_clone_state() clones the IPTFS mode data with kmemdup(). This
copies runtime objects which must not be shared with the original SA,
including the embedded sk_buff_head, hrtimers, spinlock, and in-flight
reassembly/reorder state.
If xfrm_state_migrate() fails after clone_state() but before the later
init_state() call has reinitialized those fields, the cloned state can be
destroyed by xfrm_state_gc_task() with list and timer state copied from the
original SA. With queued packets this lets the clone splice and free skbs
owned by the original IPTFS queue, leading to use-after-free and
double-free reports in iptfs_destroy_state() and skb release paths.
Reinitialize the clone's runtime state before publishing it through
x->mode_data. Because clone_state() now publishes a destroyable mode_data
object before init_state(), take the mode callback module reference there.
Avoid taking it again from __iptfs_init_state() for the same object. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: chemical: mhz19b: reject oversized serial replies
mhz19b_receive_buf() appends each serdev chunk into the fixed
MHZ19B_CMD_SIZE receive buffer and advances buf_idx by len without
checking that the chunk fits in the remaining space. A large callback
can therefore overflow st->buf before the command path validates the
reply.
Reset the reply state before each command and reject oversized serial
replies before copying them into the fixed buffer. When an oversized
reply is detected, wake the waiter and report -EMSGSIZE instead of
overwriting st->buf. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: gyro: itg3200: fix i2c read into the wrong stack location
itg3200_read_all_channels() takes `__be16 *buf' as a parameter and
fills the i2c_msg destination as `(char *)&buf'. Since `buf' is the
parameter (a pointer), `&buf' is the address of the local pointer
slot on the stack of itg3200_read_all_channels(), not the address
of the caller's scan buffer. The (char *) cast hides the type
mismatch.
i2c_transfer() therefore writes ITG3200_SCAN_ELEMENTS * sizeof(s16)
= 8 bytes into the parameter's stack slot, which is discarded when
the function returns. The caller's scan buffer in
itg3200_trigger_handler() is never written to, so
iio_push_to_buffers_with_timestamp() pushes uninitialised stack
contents to userspace via /dev/iio:deviceX every scan -- both a
functional bug (no actual gyroscope or temperature data is
delivered through the triggered buffer) and an information leak.
The non-buffered read_raw() path is unaffected: it goes through
itg3200_read_reg_s16() which uses `&out' on a local s16 value,
where that is correct.
Drop the spurious `&' so the i2c read writes into the caller's
buffer. |
| In the Linux kernel, the following vulnerability has been resolved:
Input: xpad - fix out-of-bounds access for Share button
xpadone_process_packet() receives len directly from urb->actual_length
and uses it to index the share-button byte at data[len - 18] or
data[len - 26]. Since both len and data[0] are under the device's
control, a broken controller can send a GIP_CMD_INPUT packet with
actual_length < 18 (e.g. 5 bytes) and reach this code path, causing
accesses beyond the actual array.
Fix this by calculating the offset and checking bounds against the
packet length. |
| In the Linux kernel, the following vulnerability has been resolved:
auxdisplay: line-display: fix OOB read on zero-length message_store()
linedisp_display() unconditionally reads msg[count - 1] before
checking whether count is zero, so a write of zero bytes to the
message sysfs attribute hits msg[-1]:
write(fd, "", 0);
-> message_store(..., buf, count=0)
-> linedisp_display(linedisp, buf, count=0)
-> msg[count - 1] == '\n' ; OOB read
The kernfs write buffer for that store is a 1-byte allocation
(kernfs_fop_write_iter() does kmalloc(len + 1) with len == 0),
so msg[-1] is a 1-byte read before the slab object. On a
KASAN-enabled kernel this trips an out-of-bounds report and
panics; on stock kernels it silently reads adjacent slab data
and, if that byte happens to be '\n', the following count--
wraps ssize_t 0 to -1 and is then passed to kmemdup_nul().
linedisp_display() is reached from the message_store() sysfs
callback (drivers/auxdisplay/line-display.c message attribute,
mode 0644) and from the in-tree initial-message setup with
count == -1, so the OOB path is only userspace-triggerable via
zero-byte writes; vfs_write() does not short-circuit on
count == 0 and kernfs_fop_write_iter() dispatches the store
callback regardless.
Guard the trailing-newline trim with a count check. The
existing if (!count) block then takes the clear-display path
unchanged.
Affects every auxdisplay driver that registers via
linedisp_register() / linedisp_attach(): ht16k33, max6959,
img-ascii-lcd, seg-led-gpio. |
| Improper restriction of rendered ui layers or frames in Microsoft Edge (Chromium-based) allows an unauthorized attacker to perform spoofing over a network. |
| libosmocore through 1.14.1 contains an out-of-bounds read in iuup_rx_initialization() in src/gsm/iuup.c. This allows a remote attacker to obtain sensitive information. |
