Description OSIDB Bzimport 2025-04-16 15:02:57 UTC 
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).
