The Retbleed mitigations for the Linux kernel have been merged to the various stable/supported Linux series right now.

Retbleed was made public as a new speculative execution attack exploiting return instructions. While the "good" news is Retbleed only impacts prior generations of AMD and Intel processors, the bad news is the mitigated performance impact on Linux is quite severe.
