Local privilege escalation via unchecked lpm request
Published Apr 5, 2024 · Updated Aug 27, 2024
Out-of-bounds write in Android kernel lpm.c allows local users to gain elevated privileges through a crafted low-power-management request. The lpm_req_handler function fails to validate request data before writing beyond the destination buffer. Exploitation requires local access to an affected Pixel device, needs no additional execution privileges or user interaction, and can compromise system-level confidentiality, integrity, and availability.
