Out-of-Bounds Read Vulnerability in Linux Kernel Network Framework

CVE-2026-53268

What is CVE-2026-53268?

A vulnerability exists in the Linux kernel's netfilter concerning the conntrack_irc component, which could result in an out-of-bounds read. When parsing communication commands, improper handling of the matching process may lead to undesired read attempts beyond allocated buffers. This could provoke instability or unauthorized information exposure. Given the diminishing relevance of this component with the widespread use of TLS protocols, it is suggested that this helper be deprecated.
