Local privilege escalation via bootloader bounds error
Published Feb 7, 2024 · Updated May 8, 2025
Out-of-bounds write in the Pixel bootloader in Google Android allows local users to escalate privileges without user interaction. The bootloader omits a bounds check and writes outside the intended buffer, but Google has not disclosed the affected routine or attacker-controlled input. Exploitation requires existing low-privileged local access to a supported Pixel device and results in privilege escalation; the public record identifies no narrower consequence.
