Local privilege escalation via retained DCK
Published Dec 8, 2023 · Updated Aug 2, 2024
Privilege escalation in Google Android's Pixel bootloader before the 2023-12-05 patch allows local users to retain a DCK. A bootloader logic error fails to delete the DCK during a factory reset, leaving security-sensitive key material in place. Exploitation requires local low-privileged access but no user interaction, and the retained DCK enables elevation of privilege after the reset.
