Remote privilege escalation via DRM buffer miscalculation
Published Aug 7, 2023 · Updated Nov 7, 2024
Out-of-bounds write in UNISOC DRM/oemcrypto on Android 11 and 12 allows remote authenticated users to escalate privileges. An incorrect buffer-size calculation causes oemcrypto to write beyond the allocated buffer when processing DRM input. Exploitation requires System execution privileges and can corrupt memory; further post-exploitation details are undisclosed.
