CVE-2026-13213
The Hearing Access Service HAS GATT server in subsys/bluetooth/audio/has.c installs a connection-callback set unconditionally via BTCONNCBDEFINE, so securitychanged runs for every connection that establishes security even before the application has called bthasregister. The service attribute...
CVE-2026-13213
Zephyr RTOS Bluetooth Hearing Access Service (HAS) GATT server (subsys/bluetooth/audio/has.c) contains a NULL-pointer dereference in security_changed(). The connection-callback set is installed unconditionally via BT_CONN_CB_DEFINE, so the callback fires before the application calls bt_has_regist...
CVE-2026-13213 Bluetooth HAS: NULL-pointer dereference DoS when a bonded peer reconnects before bt_has_register
The Hearing Access Service HAS GATT server in subsys/bluetooth/audio/has.c installs a connection-callback set unconditionally via BTCONNCBDEFINE, so securitychanged runs for every connection that establishes security even before the application has called bthasregister. The service attribute...
EUVD-2026-51869
Zephyr's Bluetooth host declares a GATT characteristic as two consecutive attributes: a Characteristic Declaration whose permission is hard-coded to BTGATTPERMREAD, and a Characteristic Value attribute that carries the application-specified security permissions e.g. BTGATTPERMREADENCRYPT /...
CVE-2026-10685
The Zephyr Bluetooth GATT client CCC-write response handler gattwritecccrsp in subsys/bluetooth/host/gatt.c invoked the application's params-subscribe callback after it had already called params-notifyconn, params, NULL, 0. Per the public GATT API, a notify callback with NULL data is the document...
CVE-2026-10685
CVE-2026-10685 : In Zephyr, the GATT client CCC-write response handler gatt_write_ccc_rsp() may call the application’s params->subscribe() after already invoking params->notify(conn, params, NULL, 0). A NULL data notify signals termination; calling subscribe() on the same bt_gatt_subscribe_...
CVE-2026-10680 Out-of-bounds access in Zephyr BR/EDR L2CAP configuration request handling via `uint16_t` length underflow
The Classic BR/EDR L2CAP signaling handlers l2capbrconfreq and l2capbrconfrsp in subsys/bluetooth/host/classic/l2capbr.c validated the minimum command size against buf-len the bytes remaining in the whole received PDU instead of len the per-command data length from the L2CAP signaling header...
CVE-2026-9263
The Zephyr Bluetooth controller ISO Adaptation Layer subsys/bluetooth/controller/llsw/isoal.c fails to validate the length field of a framed ISO PDU start segment. Per the Bluetooth specification a start segment sc=0 always carries a 3-byte timeoffset, so its segment-header len must be at least...
CVE-2026-10654
A race condition in the Zephyr Bluetooth Classic RFCOMM host stack subsys/bluetooth/host/classic/rfcomm.c mishandles a simultaneous bidirectional session disconnect. When the local device has initiated a session teardown state BTRFCOMMSTATEDISCONNECTING, DISC sent, RTX timer armed and the connect...

Linux Distros Unpatched Vulnerability : CVE-2026-10658
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - btisorecv in subsys/bluetooth/host/iso.c pulled the ISO SDU header 4 bytes or, when the timestamp flag is set, the timestamped SDU header 8 bytes from the inbou...
CVE-2026-10658 Out-of-bounds access in Bluetooth ISO receive (`bt_iso_recv`) due to missing SDU-header length validation
btisorecv in subsys/bluetooth/host/iso.c pulled the ISO SDU header 4 bytes or, when the timestamp flag is set, the timestamped SDU header 8 bytes from the inbound HCI ISO Data buffer via netbufpullmem without first checking buf-len. The upstream hciiso handler enforces buf-len == the...
CVE-2026-10641 Out-of-bounds write in Bluetooth HFP Hands-Free CIND indicator parsing (cind_handle_values)
Zephyr's Bluetooth Classic Hands-Free Profile HFP Hands-Free role parser subsys/bluetooth/host/classic/hfphf.c contains an out-of-bounds write. During Service Level Connection setup the HF sends AT+CIND=? and parses the AG's +CIND: response in cindhandle, which assigns a per-entry counter index a...
