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...
