SUSE CVE-2026-23456

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfconntrackh323: fix OOB read in decodeint CONS case In decodeint, the CONS case calls getbitsbs, 2 to read a length value, then calls getuintbs, len without checking that len bytes remain in the buffer. The existing...

CVE-2026-23455

A flaw was found in the Linux kernel's netfilter subsystem, specifically within the nfconntrackh323 module. This vulnerability occurs in the DecodeQ931 function when processing a zero-length value from a packet. An integer underflow during a length calculation results in a large, incorrect value...

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-2026-23456 netfilter: nf_conntrack_h323: fix OOB read in decode_int() CONS case

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfconntrackh323: fix OOB read in decodeint CONS case In decodeint, the CONS case calls getbitsbs, 2 to read a length value, then calls getuintbs, len without checking that len bytes remain in the buffer. The existing...

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...
