CVE-2024-29753

Local privilege escalation via unchecked temperature step

Published Apr 5, 2024 · Updated Mar 25, 2025

Out-of-bounds write in Google Pixel ACPM firmware allows local users to elevate privileges through a crafted temperature-control step. The tmu_set_control_temp_step function in tmu.c performs the write without first enforcing the required bounds. Exploitation needs no additional execution privileges or user interaction and can compromise confidentiality and integrity without interrupting service.
