Summary
[none]
Details

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 additional byte for the value type without verifying that the byte is present. A truncated 3-byte attribute (for example 09 00 09) therefore reaches netbufsimplepull() with insufficient remaining length, triggering the __ASSERTNOMSG(buf->len >= len) check and a kernel panic in assert-enabled builds (denial of service). In builds where assertions are disabled, parsing may continue past the end of the available buffer, leading to an out-of-bounds read and undefined behavior.
