Local code execution via stack buffer overflow
Published Sep 13, 2024 · Updated Sep 17, 2024
Stack-based buffer overflow in Lenovo notebook BIOS firmware allows local users with elevated privileges to execute arbitrary code. Lenovo has not published the affected component, attacker-controlled input, or the unsafe operation that overruns the stack buffer. Exploitation requires high local privileges and can compromise confidentiality, integrity, and availability through code execution.
