CVE-2025-22047 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: x86/microcode/AMD: Fix __apply_microcode_amd()'s return value When verify_sha256_digest() fails, __apply_microcode_amd() should propagate the failure by returning false (and not -1 which is promoted to true).. EPSS estimates a 0.17% chance of exploitation in the next 30 days.
