====================================================
The IPv6 fragmentation implementation in the Linux kernel through 4.11.1 does
not consider that the nexthdr field may be associated with an invalid option,
which allows local users to cause a denial of service (out-of-bounds read and
BUG) or possibly have unspecified other impact via crafted socket and send
system calls.
