CVE-2025-0032
Improper cleanup in AMD CPU microcode patch loading could allow an attacker with local administrator privilege to load malicious CPU microcode, potentially resulting in loss of integrity of x86 instruction execution.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.15%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
