Last modified
CVE-2017-5897 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. 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.. EPSS estimates a 4.95% chance of exploitation in the next 30 days.
