CVE-2022-48183

Physical access bypass via failed tamper detection

Published Oct 9, 2023 · Updated Sep 19, 2024

Improper physical access control in affected Lenovo ThinkPad T14s Gen 3 and X13 Gen 3 BIOS allows physically proximate attackers unauthorized access. Under specific, undisclosed circumstances, the BIOS tamper-detection mechanism fails to trigger when physical tampering occurs. Physical access to an affected system is required, and Lenovo reports integrity and availability impact without confidentiality impact.
