      "title": "ipvs: clear IPv4 options after rebasing tunnel ICMP errors",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nipvs: clear IPv4 options after rebasing tunnel ICMP errors\n\nip_vs_in_icmp() rebases an skb from the outer ICMP packet to the\nquoted original request before passing it to icmp_send(). However,\nIPCB(skb)->opt still describes the outer IPv4 header.\n\nA timestamp option in the outer header can therefore leave an offset\nthat points into the quoted transport header after the rebase.\n__ip_options_echo() treats a byte at that stale location as the option\nlength and copies it into the fixed-size option storage on the\n__icmp_send() stack, causing a stack out-of-bounds write.\n\nClear the stale option metadata after resetting the network header.\nKeep the remaining control block fields, including the ingress\ninterface used by the ICMP response path.",
