Dan Carpenter a23a2b5128 6lowpan: Off by one handling ->nexthdr ... [ Upstream commit f57c4bbf34439531adccd7d3a4ecc14f409c1399 ] NEXTHDR_MAX is 255. What happens here is that we take a u8 value "hdr->nexthdr" from the network and then look it up in lowpan_nexthdr_nhcs[]. The problem is that if hdr->nexthdr is 0xff then we read one element beyond the end of the array so the array needs to be one element larger.
