CVE-2022-29900
Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution under certain microarchitecture-dependent conditions.
MEDIUM 6.5EPSS 3.80%
Does this matter?
Lower severity and a low EPSS score (3.80%). Track it; it rarely justifies an emergency change on its own.
