CVE-2021-0363

Local privilege escalation via unchecked command data

Published Feb 2, 2021 · Updated Aug 3, 2024

Command injection in Google Cloud Android 10 and 11 mobile_log_d allows local users with System privileges to gain elevated privileges. The daemon omits a bounds check when processing command input, permitting command injection; no affected function, input field, or command-construction path is public. Exploitation is local, requires existing System execution privileges, and needs no user interaction, limiting exposure to already privileged code on affected devices.
