CVE-2017-5897
The ip6gre_err function in net/ipv6/ip6_gre.c in the Linux kernel allows remote attackers to have unspecified impact via vectors involving GRE flags in an IPv6 packet, which trigger an out-of-bounds access.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.58%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
