Description
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.
