kernel: netfilter: nf_conntrack_h323: check for zero length in DecodeQ931()

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-2026-43233

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfconntrackh323: fix OOB read in decodechoice In decodechoice, the boundary check before getlen uses the variable len, which is still 0 from its initialization at the top of the function: unsigned int type, ext, len = ...

Linux Distros Unpatched Vulnerability : CVE-2026-23456

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - 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...

Linux Distros Unpatched Vulnerability : CVE-2026-23455

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - netfilter: nfconntrackh323: check for zero length in DecodeQ931 In DecodeQ931, the UserUserIE code path reads a 16-bit length from the packet, then decrements i...

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-2024-26851

CVE-2024-26851 concerns the Linux kernel netfilter nf_conntrack_h323 path. The issue arises when decoding H.323 ras messages: an abnormal skb->data can cause the extension bitmap length to exceed 32, leading to a length-based shift that may become negative and trigger UBSAN reports. The workar...
