Description

The Bluetooth Mesh On-Demand Private Proxy solicitation handler in subsys/bluetooth/mesh/solicitation.c copies a received Solicitation PDU into a fixed 17-byte stack buffer without bounding the source length. In sol_pdu_decrypt(), out is allocated as NET_BUF_SIMPLE(17) and then filled with net_buf_simple_add_mem(out, in->data, in->len); net_buf_simple_add() guards its tailroom only with __ASSERT_NO_MSG, which is compiled out in production builds, so when in->len > 17 the underlying memcpy writes
