kernel: ipv6: validate extension header length before copying to cmsg

A flaw was found in the Linux kernel's IPv6 networking stack. An unprivileged local user could exploit a vulnerability in how IPv6 extension header lengths are handled. By manipulating these headers using nftables, an attacker can trigger an out-of-bounds read, leading to information disclosure...

SUSE CVE-2026-110661

CGNS through 4.5.2 contains a stack out-of-bounds read vulnerability in ADFIreadnodeheader that allows attackers to crash applications by supplying crafted ADF node headers. Attackers can craft .cgns or .adf files whose non-NUL-terminated end tag causes ADFIstridxc to scan past disknodedata,...

SUSE CVE-2026-111131

libxmp through 4.7.4 contains an off-by-one stack out-of-bounds read vulnerability in the prowizard P61A depacker depackp61a in src/loaders/prowizard/p61a.c.

Stack overflow when parsing deeply nested input in pest_grammars

Impact In affected versions, parsing deeply nested input with pestgrammars::json::JsonParser can exhaust the native stack and abort the hosting process. Applications that accept attacker-controlled JSON without suitable resource limits may therefore be vulnerable to denial of service. The reporte...
