Local service interruption via incorrect status check
Published Sep 4, 2023 · Updated Oct 10, 2024
Improper input validation in MediaTek cmdq on Android 12.0 and 13.0 allows local users with System privileges to cause a service interruption. An incorrect status check permits an out-of-bounds read in the cmdq component. Exploitation requires System-level execution privileges but no user interaction, and the documented consequence is local denial of service rather than data disclosure or code execution.
