Arbitrary code execution via unchecked buffer copy
Published Nov 8, 2023 · Updated Sep 3, 2024
Buffer overflow in FmpSipoCapsuleDriver in Lenovo IdeaPad Duet 3 10IGL5 before EQCN39WW allows local users to execute arbitrary code. The driver copies an input buffer without verifying that it fits the destination buffer, allowing memory to be overwritten. Exploitation requires elevated local privileges and allows attacker-controlled code to run in the firmware driver's context.
