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.
