CVE-2026-53268
8.2
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: conntrack_irc: fix possible out-of-bounds read
When parsing fails after we've matched the command string we should bail out instead of trying to match a different command.
This helper should be deprecated, given prevalence of TLS I doubt it has any relevance in 2026.
