Local system crash via out-of-bounds write
Published Aug 13, 2026 · Updated Aug 13, 2026
Out-of-bounds write in Lenovo ELAN TrackPoint drivers allows local authenticated users to cause a system crash. Lenovo and ELAN have not disclosed the affected routine, the input that reaches it, or the specific bounds-checking failure. Exploitation requires local low-privileged access, high attack complexity, and an additional driver-path precondition; the reported impact is a crash without confidentiality or integrity loss.
