CVE-2021-26341

Public on 2022-03-09

Modified on 2023-01-18

Description

AMD recommends using a software mitigation for this issue, which the kernel is enabling by default. The Linux kernel will use the generic retpoline software mitigation, instead of the specialized AMD one, on AMD instances (*5a*). This is done by default, and no administrator action is needed.
