kernel: xfrm: ah6: validate routing header segments_left

A flaw was found in the Linux kernel's xfrm subsystem, specifically within the AH6 Authentication Header for IPv6 module. The ipv6rearrangerthdr function does not properly validate the segmentsleft field in routing headers when processing raw IPv6 HDRINCL packets. This oversight allows an attacke...
