Administrator-triggered state changes and unexpected failures

Published Sep 12, 2022 · Updated Sep 16, 2024

Unchecked return handling in Dell Client Platform BIOS on pre-21Q4 platforms allows local users to alter system state or trigger failures. Dell has not published the affected firmware routine, the unchecked operation, or the return value that is ignored. Exploitation requires local authenticated administrator privileges and high attack complexity; reported consequences are system-state changes and unexpected failures.
