Cross-Process Information Leak, April 30, 2024 (2024-04-30)
(AMD-SB-7008)

Summary:

Under specific microarchitectural circumstances, a register in “Zen 2” CPUs may not be written to 0 correctly. This may cause data from another process and/or thread to be stored in the YMM register, which may allow an attacker to potentially access sensitive information.

Affected Platforms and BIOS version numbers that contain the fix:

AMD Rome/Milan
S8030
  • V2.03 for S8030GM4NE-2T
  • V4.03 for S8030GM2NE
