The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-098771 advisory. In the Linux kernel, the following vulnerability has been resolved: netfilter: nfconntrackh323: check for zero length in DecodeQ931 In DecodeQ931, the UserUserIE cod...

The vulnerability of the DecodeQ931() function in the net/netfilter/nf_conntrack_h323_asn1.c module of the netfilter kernel in the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of protected information.

The vulnerability of the DecodeQ931 function in the net/netfilter/nfconntrackh323asn1.c module of the netfilter component in the Linux operating system is related to the issue of data being written outside of the buffer. Exploiting this vulnerability could allow a remote attacker to compromise th...

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...
