| A flaw was found in GIMP. This issue is a heap buffer over-read in GIMP PCX file loader due to an off-by-one error. A remote attacker could exploit this by convincing a user to open a specially crafted PCX image. Successful exploitation could lead to out-of-bounds memory disclosure and a possible application crash, resulting in a Denial of Service (DoS). |
| Determined not a vulnerability |
| In multiple functions of VideoRtpPayloadDecoderNode.cpp, there is a possible out of bounds write due to an integer overflow. This could lead to remote code execution with no additional execution privileges needed. User interaction is not needed for exploitation. |
| In Modem, there is a possible way to trigger a modem crash during a SIP REFER request due to memory corruption. This could lead to remote code execution with no additional execution privileges needed. User interaction is not needed for exploitation. |
| In the Linux kernel, the following vulnerability has been resolved:
libceph: prevent potential out-of-bounds reads in handle_auth_done()
Perform an explicit bounds check on payload_len to avoid a possible
out-of-bounds access in the callout.

| FreeRDP before 3.26.0 contains a heap-buffer-overflow vulnerability in gdi_CacheToSurface that allows remote attackers to write out-of-bounds heap memory. The vulnerability occurs because rectangle validation clamps coordinates to UINT16_MAX but performs copy operations using unclamped cache entry dimensions, enabling malicious RDP servers to trigger large out-of-bounds writes and potentially achieve remote code execution or client crash. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/vmwgfx: Validate command header size against SVGA_CMD_MAX_DATASIZE
This data originates from userspace and is used in buffer offset
calculations which could potentially overflow causing an out-of-bounds
access. |
| OpenClaw before 2026.5.26 contains a hostname validation vulnerability allowing attackers to bypass blocklist comparisons using trailing-dot notation in model or workspace-derived URLs. Attackers can exploit inconsistent hostname checks to reach destinations that operators intended to block through hostname policies. |
| DNG SDK versions 1.7.1 2536 and earlier are affected by an out-of-bounds read vulnerability that could lead to disclosure of sensitive memory. An attacker could leverage this vulnerability to disclose sensitive information. Exploitation of this issue requires user interaction in that a victim must open a malicious file. |

| In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: fw_tracer, Validate format string parameters
Add validation for format string parameters in the firmware tracer to
prevent potential security vulnerabilities and crashes from malformed
format strings received from firmware.
The firmware tracer receives format strings from the device firmware and
uses them to format trace messages. Without proper validation, bad
firmware could provide format strings with invalid format specifiers
(e.g., %s, %p, %n) that could lead to crashes, or other undefined
behavior.
Add mlx5_tracer_validate_params() to validate that all format specifiers
in trace strings are limited to safe integer/hex formats (%x, %d, %i,
%u, %llx, %lx, etc.). Reject strings containing other format types that
could be used to access arbitrary memory or cause crashes.
Invalid format strings are added to the trace output for visibility with
"BAD_FORMAT: " prefix. |
| In the Linux kernel, the following vulnerability has been resolved:
mm/damon/core: validate damos_quota_goal->nid for node_mem_{used,free}_bp
Patch series "mm/damon/core: validate damos_quota_goal->nid".
node_mem[cg]_{used,free}_bp DAMOS quota goals receive the node id. The
node id is used for si_meminfo_node() and NODE_DATA() without proper
validation. As a result, privileged users can trigger an out of bounds
memory access using DAMON_SYSFS. Fix the issues.
The issue was originally reported [1] with a fix by another author. The
original author announced [2] that they will stop working including the
fix that was still in the review stage. Hence I'm restarting this.
This patch (of 2):
Users can set damos_quota_goal->nid with arbitrary value for
node_mem_{used,free}_bp. But DAMON core is using those for
si_meminfo_node() without the validation of the value. This can result in
out of bounds memory access. The issue can actually triggered using DAMON
user-space tool (damo), like below.
$ sudo ./damo start --damos_action stat \
--damos_quota_goal node_mem_used_bp 50% -1 \
--damos_quota_interval 1s
$ sudo dmesg
[...]
[ 65.565986] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000098
Fix this issue by adding the validation of the given node. If an invalid
node id is given, it returns 0% for used memory ratio, and 100% for free
memory ratio. |
| In the Linux kernel, the following vulnerability has been resolved:
misc: ibmasm: fix OOB MMIO read in ibmasm_handle_mouse_interrupt()
ibmasm_handle_mouse_interrupt() performs an out-of-bounds MMIO read
when the queue reader or writer index from hardware exceeds
REMOTE_QUEUE_SIZE (60).
A compromised service processor can trigger this by writing an
out-of-range value to the reader or writer MMIO register before
asserting an interrupt. Since writer is re-read from hardware on
every loop iteration, it can also be set to an out-of-range value
after the loop has already started.
The root cause is that get_queue_reader() and get_queue_writer() return
raw readl() values that are passed directly into get_queue_entry(),
which computes:
queue_begin + reader * sizeof(struct remote_input)
with no bounds check. This unchecked MMIO address is then passed to
memcpy_fromio(), reading 8 bytes from unintended device registers.
For sufficiently large values the address falls outside the PCI BAR
mapping entirely, triggering a machine check exception.
Fix by checking both indices against REMOTE_QUEUE_SIZE at the top of
the loop body, before any call to get_queue_entry(). On an out-of-range
value, reset the reader register to 0 via set_queue_reader() before
breaking, so that normal queue operation can resume if the corrupted
hardware state is transient. |
| In the Linux kernel, the following vulnerability has been resolved:
dm mirror: fix integer overflow in create_dirty_log()
The argument count calculation in create_dirty_log() performs
`*args_used = 2 + param_count` before validating against argc. When a
user provides a param_count close to UINT_MAX via the device mapper
table string, this unsigned addition wraps around to a small value,
causing the subsequent `argc < *args_used` check to be bypassed.
The overflowed param_count is then passed as argc to dm_dirty_log_create(),
where it can cause out-of-bounds reads on the argv array.
Fix by comparing param_count against argc - 2 before performing the
addition, following the same pattern used by parse_features() in the
same file. Since argc >= 2 is already guaranteed, the subtraction is
safe. |
| In the Linux kernel, the following vulnerability has been resolved:
libceph: Prevent potential null-ptr-deref in ceph_handle_auth_reply()
If a message of type CEPH_MSG_AUTH_REPLY contains a zero value for both
protocol and result, this is currently not treated as an error. In case
of ac->negotiating == true and ac->protocol > 0, this leads to setting
ac->protocol = 0 and ac->ops = NULL. Thereafter, the check for
ac->protocol != protocol returns false, and init_protocol() is not
called. Subsequently, ac->ops->handle_reply() is called, which leads to
a null pointer dereference, because ac->ops is still NULL.
This patch changes the check for ac->protocol != protocol to
!ac->protocol, as this also includes the case when the protocol was set
to zero in the message. This causes the message to be treated as
containing a bad auth protocol. |
| Kitty is a cross-platform GPU based terminal. In versions prior to 0.47.3, kitty's OSC 21 (color-control) query reply reflects attacker-controlled bytes, including newlines, into the shell's input without sanitization. Version 0.47.3 fixes the issue. |
| A security vulnerability has been detected in D-Link DCS-935L 1.10.01. This issue affects the function snprintf of the file /web/cgi-bin/greece/rhea of the component HTTP Handler. Such manipulation of the argument data leads to format string. The attack may be launched remotely. The exploit has been disclosed publicly and may be used. |
| In the Linux kernel, the following vulnerability has been resolved:
hwmon: (pt5161l) Fix bugs in pt5161l_read_block_data()
Fix two bugs in pt5161l_read_block_data():
1. Buffer overrun: The local buffer rbuf is declared as u8 rbuf[24],
but i2c_smbus_read_block_data() can return up to
I2C_SMBUS_BLOCK_MAX (32) bytes. The i2c-core copies the data into
the caller's buffer before the return value can be checked, so
the post-read length validation does not prevent a stack overrun
if a device returns more than 24 bytes. Resize the buffer to
I2C_SMBUS_BLOCK_MAX.
2. Unexpected positive return on length mismatch: When all three
retries are exhausted because the device returns data with an
unexpected length, i2c_smbus_read_block_data() returns a positive
byte count. The function returns this directly, and callers treat
any non-negative return as success, processing stale or incomplete
buffer contents. Return -EIO when retries are exhausted with a
positive return value, preserving the negative error code on I2C
failure. |
| In the Linux kernel, the following vulnerability has been resolved:
ext2: reject inodes with zero i_nlink and valid mode in ext2_iget()
ext2_iget() already rejects inodes with i_nlink == 0 when i_mode is
zero or i_dtime is set, treating them as deleted. However, the case of
i_nlink == 0 with a non-zero mode and zero dtime slips through. Since
ext2 has no orphan list, such a combination can only result from
filesystem corruption - a legitimate inode deletion always sets either
i_dtime or clears i_mode before freeing the inode.
A crafted image can exploit this gap to present such an inode to the
VFS, which then triggers WARN_ON inside drop_nlink() (fs/inode.c) via
ext2_unlink(), ext2_rename() and ext2_rmdir():

Extend the existing i_nlink == 0 check to also catch this case,
reporting the corruption via ext2_error() and returning -EFSCORRUPTED.
This rejects the inode at load time and prevents it from reaching any
of the namei.c paths.

| In the Linux kernel, the following vulnerability has been resolved:
rxgk: Fix potential integer overflow in length check
Fix potential integer overflow in rxgk_extract_token() when checking the
length of the ticket. Rather than rounding up the value to be tested
(which might overflow), round down the size of the available data. |
