CVE-2026-85036

The Bluetooth Classic AVDTP layer in Zephyr RTOS is vulnerable to a denial of service (DoS) due to improper session memory re-initialization. When a session is disconnected, bt_avdtp_l2cap_disconnected() submits a release work item to the system work queue. If a new signaling connection is immedi...

CVE-2026-19939

The AVDTP signalling layer arms a 6-second command timeout AVDTPTIMEOUT in avdtpsendcmd whenever the local device issues an AVDTP request. Every response handler in subsys/bluetooth/host/classic/avdtp.c cancels session-timeoutwork before clearing the pending request, but btavdtpl2capdisconnected...

CVE-2026-19939

The Bluetooth Classic AVDTP signalling layer in the Zephyr RTOS (with CONFIG_BT_A2DP enabled) contains a vulnerability where a stale timeout work item can cause kernel timeout-list corruption . When a remote BR/EDR peer disconnects an AVDTP signalling channel without responding to a request, the ...
