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."
