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-2026-10651

The CVE-2026-10651 affects Zephyr’s Bluetooth Classic SDP parser (subsys/bluetooth/host/classic/sdp.c) where bt_sdp_parse_attribute() reads a 3-byte attribute (1-byte type, 2-byte id) but then unconditionally pulls an extra value type byte without verifying remaining length. A truncated 3-byte at...

CVE-2026-10651 Bluetooth Classic SDP parser truncation bug in bt_sdp_parse_attribute() leads to reachable assertion and possible out-of-bounds read

A malformed Bluetooth Classic SDP attribute can trigger a reachable assertion in Zephyr's SDP parser. In subsys/bluetooth/host/classic/sdp.c, btsdpparseattribute accepts an input buffer once it contains the 1-byte attribute type and 2-byte attribute id, but then unconditionally pulls an additiona...
