Linux Kernel AMD Erratum Table Off-by-One Vulnerability

A vulnerability in the Linux kernel's handling of AMD microcode erratum tables can lead to out-of-bounds reads. This issue arises because the NULL terminator at the end of the 'erratum_1386_microcode' array was removed during a transition in how CPU descriptions are managed. As a result, readers may inadvertently access memory beyond the intended array boundary.

Impact

Exploitation of this vulnerability could cause out-of-bounds memory access, which may lead to undefined behavior, including potential memory corruption.
