Answer in brief
CVE-2025-22047 records a Unknown severity vulnerability in x86/microcode/AMD: Fix __apply_microcode_amd()'s return value. The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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).
