While pskb_network_may_pull() ensures the packet data is\nlinear starting from the network header, it does not set or adjust the\ntransport header offset.\n\nDereferencing icmp6_hdr(skb) can therefore access out-of-bounds memory.\n\nFetch the icmp6hdr directly after ipv6hdr following pskb_network_may_pull(),\nand reload ipv6hdr in case pskb_may_pull() reallocated skb->head.\nAlso remove the unused bond argument from alb_determine_nd().","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/27314f96d29b54e815e7a9b84c3273f1895e68e2","tags":[]},{"url":"https://git.kernel.org/stable/c/3b178894931a268c09126a5b53630f343e10e296","tags":[]},{"url":"https://git.kernel.org/stable/c/70f3995830d3f1e79faa14eb0605914f778feca9","tags":[]},{"url":"https://git.kernel.org/stable/c/e39cf90bd856443542b97933289749fca07476bf","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
