Local privilege escalation via unvalidated da input
Published Mar 4, 2024 · Updated Aug 1, 2024
Out-of-bounds write in the da component on MediaTek chipsets running Android 12.0 through 14.0 allows local users to gain privileges. The da component fails to validate an unspecified input before writing outside the intended buffer. Exploitation requires existing System execution privileges, needs no user interaction, and can elevate execution locally.
