CVE-2026-85218

Description
A double stack-based buffer overflow was found in the BlueZ AVRCP controller implementation. A nearby BR/EDR peripheral can send a crafted AVRCP player-settings response that supplies an attacker-controlled attribute count, causing avrcp_list_player_attributes_rsp() and avrcp_get_current_player_value() in profiles/audio/avrcp.c to write attacker-controlled data past fixed-size stack buffers, potentially leading to a crash or code execution in the bluetoothd daemon.
