CVE-2026-43386

In the Linux kernel, the following vulnerability has been resolved: staging: rtl8723bs: fix potential out-of-bounds read in rtwrestructwmmie The current code checks 'i + 5 inlen' at the end of the if statement. However, it accesses 'iniei + 5' before that check, which can lead to an out-of-bounds...

CVE-2026-43442

The CVE-2026-43442 issue affects the Linux kernel io_uring subsystem: when IORING_SETUP_SQE_MIXED is used without IORING_SETUP_NO_SQARRAY, a flawed 128-byte SQE bounds check validates the logical SQ head instead of the physical SQE index. This can let an unprivileged local user remap a logical po...

CVE-2026-43406 libceph: prevent potential out-of-bounds reads in process_message_header()

In the Linux kernel, the following vulnerability has been resolved: libceph: prevent potential out-of-bounds reads in processmessageheader If the message frame is maliciously corrupted in a way that the length of the control segment ends up being less than the size of the message header or a...

CVE-2026-43406

CVE-2026-43406 affects the Linux kernel libceph component. The issue is in process_message_header() where, if a message frame is corrupted or misrepresented, an out-of-bounds read may occur due to a missing explicit bounds check before decoding the header. The vulnerability can enable remote expl...

CVE-2026-43398

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: add upper bound check on user inputs in wait ioctl Huge input values in amdgpuuserqwaitioctl can lead to a OOM and could be exploited. So check these input value against AMDGPUUSERQMAXHANDLES which is big enough value...

CVE-2026-43316

In the Linux kernel, the following vulnerability has been resolved: media: solo6x10: Check for out of bounds chipid Clang with CONFIGUBSANSHIFT=y noticed a condition where a signed type literal "1" is an "int" could end up being shifted beyond 32 bits, so instrumentation was added and due to the...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: dpaa2-switch: Fixed an issue where an interrupt storm occurred after receiving a corrupted ifid in the IRQ handler. Commit 31a7a0bbeb00 “dpaa2-switch”: added a range check for ifid in the IRQ handler introduces a mechanism to...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: A bounds check was added to rungethighestvcn. rungethighestvcn parses a packed NTFS mapping-pairs buffer without any length limitation, relying solely on a 0x00 terminator to stop it. A crafted $LogFile UpdateMappingPai...

PT-2026-39067

This happens if a message frame is corrupted, causing the control...

pyOpenSSL: DTLS cookie callback buffer overflow

A flaw was found in pyOpenSSL. The setcookiegeneratecallback callback function can be used to generate DTLS cookies. When the callback returns a cookie string or byte sequence longer than 256 bytes, a buffer overflow can be triggered due to a missing bounds checking before copying the data to a...

imageproc: integer overflow in kernel size check leads to out-of-bounds read

A bounds verification of a slice storage of a 2-dimensional matrix's coefficients a kernel would compare the total size against the product of individual dimensions. This would erroneously cast after the multiplication and consequently fail to detect possible violations when overflow occurs...

GHSA-QG8R-F7X3-25F7 imageproc: Out-of-bounds read via NaN coordinates in bilinear/bicubic sampling

A bounds check was performed in floating points before a cast to the index passed to an unchecked access function. This checked considered NaN cases improperly, causing them to succeed the check instead of failing it. The floating point coordinate is under caller control by passing a selected...

GHSA-5QV7-J6W5-FR4M imageproc has fragile bounds check when sampling from image

A read of pixels was coded as modifying coordinates to lie within the image bounds. It would calculate a coordinate by adding a constant to an input and taking the minimum of the resulting coordinate and 'dimension - 1'. This would not protect against malicious inputs that could overflow the...
