CVE-2026-23455

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfconntrackh323: check for zero length in DecodeQ931 In DecodeQ931, the UserUserIE code path reads a 16-bit length from the packet, then decrements it by 1 to skip the protocol discriminator byte before passing it to...

CVE-2026-23456

In the Linux kernel, CVE-2026-23456 concerns nf_conntrack_h323: decode_int() in CONS reads the length with get_bits() and then calls get_uint() without ensuring enough bytes remain, causing a 1–4 byte slab-out-of-bounds read. A boundary check for len after get_bits() and before get_uint() has bee...

CVE-2026-23455

TL;DR : CVE-2026-23455 is a Linux kernel vulnerability in netfilter nf_conntrack_h323, fixed by adding a check so the decoded length remains positive after subtracting the protocol discriminator. Affected component : Linux kernel, nf_conntrack_h323 DecodeQ931() UserUserIE path. Root cause : The d...
