Local privilege escalation via ufdt_convert memory corruption
Published Dec 16, 2022 · Updated Apr 21, 2025
Out-of-bounds read in Android kernel ufdt_convert allows local users with System privileges to escalate privileges without user interaction. The ufdt_convert component reads beyond a memory buffer, but Google has not disclosed the affected function, input path, or faulty memory operation. Exploitation requires local System execution privileges and no user interaction; the documented consequence is privilege escalation.
