Local denial of service via unchecked command range
Published Sep 4, 2023 · Updated Oct 8, 2024
Improper input validation in MediaTek imgsys_cmdq allows local users to cause denial of service through an out-of-bounds read. The component reads beyond a valid range because it fails to validate an input range before processing a command. Exploitation requires System execution privileges and user interaction, and the documented consequence is limited to local service interruption.
