CVE-2025-21991

The CVE-2025-21991 issue affects the Linux kernel’s AMD microcode loader for x86. It could trigger an out-of-bounds access when iterating NUMA nodes with empty or CPU-less nodes, potentially accessing cpu_data beyond its bounds during a microcode update. The root cause is that load_microcode_amd(...
