Summary
amd64-microcode vulnerabilities
Details

Oleksii Oleksenko, Cedric Fournet, Jana Hofmann, Boris Köpf, Stavros Volos, and Flavien Solt discovered that some AMD processors may allow an attacker to infer data from previous stores. A local attacker could possibly use this issue to expose sensitive information. This update provides the updated microcode mitigations required for the corresponding Linux kernel update.
