Privilege escalation via mismatched AVDT reply type
Published Sep 2, 2025 · Updated Feb 26, 2026
Type confusion in Android 13 through 15 Bluetooth allows remote attackers to escalate privileges through a malformed AVDT reply. The avdt_msg_ind handler accepted a response or rejection whose signal did not match the pending AVDT command, causing an incompatible interpretation and eventual out-of-bounds access. Exploitation requires a paired device but no user interaction or additional execution privileges, and the resulting memory corruption enables privilege escalation.
