Summary
AMI AptioV firmware from AptioV_5.0 before AptioV_5.043 contains a flaw where BIOS code accesses a buffer using an incorrect length value (CWE-805). A local user with low privileges can trigger buffer overflows and memory corruption in the BIOS. Successful exploitation could lead to arbitrary code execution with impact on confidentiality, integrity, and availability.
