CVE-2026-19940

The Bluetooth Classic Hands-Free Profile Audio Gateway implementation in subsys/bluetooth/host/classic/hfpag.c keeps its struct bthfpag objects in a static pool indexed by ACL connection index. On link teardown, hfpagdisconnected cancels ag-txwork and the per-call work items and then clears...

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-2026-19940

The Bluetooth Classic Hands-Free Profile Audio Gateway implementation in subsys/bluetooth/host/classic/hfp_ag.c is vulnerable to a memory corruption issue. When a link is torn down, the hfp_ag_disconnected() function fails to cancel the ag->ongoing_call_work item. If a new connection reuses th...
