NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-5_14_21-150500_55_49-default package and not the kernel-livepatch-5_14_21-150500_55_49-default package as distributed by SLES. See How to fix? for SLES:15.5 relevant fixed versions and status.

The IPv6 implementation in the Linux kernel before 6.3 has a net/ipv6/route.c max_size threshold that can be consumed easily, e.g., leading to a denial of service (network is unreachable errors) when IPv6 packets are sent in a loop via a raw socket.
