Local privilege escalation via camera middleware double free
Published Sep 7, 2026 · Updated Sep 8, 2026
Double free in MediaTek chipset camera middleware allows local users with System privilege to gain higher privileges without interaction. The middleware frees the same memory allocation twice, but MediaTek has not disclosed the affected function or attacker-controlled trigger. Exploitation requires prior System privilege on a device using one of the listed chipsets, and no user interaction is required.
