Description SMASH SMASH 2024-01-29 14:06:30 UTC

A race condition was found in the Linux Kernel. Under certain conditions, an unauthenticated attacker from an adjacent network could send an ICMPv6 router advertisement packet, causing arbitrary code execution.

I don't think this affects us in any way. The commit introducing the problem (3dec89b14d37) got merged in 6.6-rc1 and we didn't seem to backport it to our branches. Reassigning back to security team.

not affecting any streams except tumbleweed which gets new kernels
