A NULL pointer dereference bug was found in the rocker device (emulated ethernet switch) of QEMU. The rocker_tlv_parse_nested() function could return early because of no group ids in the group_tlvs array. In such case, the tlvs pointer is NULL and tlvs[i + 1] in the next for-loop iteration ends up dereferencing a NULL pointer.
