CWE ID 125
Summary
CVE-2024-56721 is a vulnerability in the Linux kernel that affects x86/CPU/AMD systems. The issue lies in the erratum_1386_microcode array, which fails to terminate properly due to the lack of an empty entry at its end. Consequently, x86_match_cpu_with_stepping() function continues to iterate the array beyond its limits, posing a potential security risk. This vulnerability has been mitigated by adding an empty entry to the erratum_1386_microcode array to prevent unintended array access.
