CVE-2026-18748

The Bluetooth Classic A2DP host stores a codec Information Element IE in struct bta2dpcodecie, a one-byte len field plus a fixed 8-byte codecie array. When an AVDTP peer sent a codec IE longer than 8 bytes, a2dpprocessconfigind in subsys/bluetooth/host/classic/a2dp.c copied only the first 8 bytes...

CVE-2026-18748

The Bluetooth Classic A2DP host is vulnerable to an out-of-bounds read due to improper handling of the codec Information Element (IE). Specifically, a2dp_process_config_ind() in subsys/bluetooth/host/classic/a2dp.c fails to validate the length of the codec IE, copying only the first 8 bytes while...

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 ...

CVE-2026-93015

BlueKitchen BTstack through 1.8.2 fails to validate the peer-reported endpoint count against table bounds in A2DP stream endpoint discovery. A bonded peer can send an AVDTP DISCOVER response with more endpoints than the fixed table holds, causing out-of-bounds writes that corrupt adjacent static...
