Ralf Spenneberg discovered that the ext4 implementation in the Linux kernel
did not properly validate meta block groups. An attacker with physical
access could use this to specially craft an ext4 image that causes a denial

CVE-2017-5897 [CRITICAL] CWE-125 kernel: ip6_gre: Invalid reads in ip6gre_err
kernel: ip6_gre: Invalid reads in ip6gre_err
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.
An issue was found in the Linux kernel ipv6 implementation of GRE tunnels which allows a remote attacker to trigger an out-of-bounds access. At this time we understand no trust barrier has been crossed and there is no security implications in this flaw.
Statement: Red Hat Enterprise Linux 5 and 6 are not affected as they do not include this code.
Red Hat Enterprise Linux 7, MRG and realtime kernels contain the code, but are not affected. At this time we do not believe there is a denial of service, memory leak, privilege escalation or trust
