Unauthorized access via failed BIOS tamper detection
Published Oct 9, 2023 · Updated Sep 19, 2024
Improper physical access control in Lenovo ThinkPad T14s Gen 3 and X13 Gen 3 BIOS allows physically proximate attackers to gain unauthorized access. The BIOS tamper-detection mechanism fails to trigger under specific circumstances, but Lenovo has not disclosed the triggering condition or underlying operation. Physical access is required, and the resulting access can alter system integrity or interrupt operation without reported data disclosure.
