Local privilege escalation to System Management Mode (SMM) in Lenovo ThinkPad BIOS firmware allows a high-privileged local user to execute arbitrary code at one of the most privileged execution rings on x86 hardware. The flaw, an out-of-bounds write (CWE-787) discovered by Lenovo during an internal security assessment, affects a wide range of current-generation ThinkPad models including X1 Carbon 13th Gen, X13 Gen 6, T14s Gen 6, P14s/P16v Gen 3, L13/L14/L16 Gen 6, and E16 Gen 3. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
Arbitrary privileged memory read/write in Lenovo ThinkPad embedded controller (EC) firmware allows a local administrator on affected ThinkPad models (X13 Gen 6, X1 Carbon 13th Gen, P16v Gen 3, L16 Gen 1/2, T14s Gen 6, P14s Gen 6, L13 Gen 6, L14 Gen 6) to access or modify protected memory regions. Discovered during Lenovo's internal security assessment, the issue is rated CVSS 4.0 8.4 (High) and there is no public exploit identified at time of analysis, with no CISA KEV listing. Despite the high score, exploitation requires high privileges and local access, narrowing realistic abuse to attackers who already have admin on the host or to supply-chain/insider scenarios.
