Title
x86/microcode/AMD: Fix __apply_microcode_amd()'s return value
Summary
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).
