A malicious or malformed Thunderbolt device can set dual_link_port_nr beyond the allocated sw->ports[] (max_port_number + 1 entries), producing an out-of-bounds tb_port pointer that is stored and later dereferenced. A malicious or malformed Thunderbolt device can provide an invalid port number, leading to an out-of-bounds memory access. This can result in memory corruption and…
