"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: skbuff: fix pull-bound underflow in skb_checksum_setup_ipv6()\n\nskb_maybe_pull_tail() subtracts skb_headlen(skb) from the unsigned max\nargument and passes the result to __pskb_pull_tail() as a signed int. The\nfunction does not ensure that max is at least skb_headlen(skb).\n\nThis can happen while parsing IPv6 extension headers when an skb already\nhas a linear area larger than MAX_IPV6_HDR_LEN. Once the parser needs data\nbeyond the linear area, max - skb_headlen(skb) wraps and is converted to a\nnegative delta. __pskb_pull_tail() then passes that negative length to\nskb_copy_bits(), where it can become a very large copy length.\n\nPass the requested length itself as the pull bound at the three\nextension-header call sites, so the delta can no longer go negative."
