CVE-2024-56751 is a medium severity vulnerability in the Linux kernel's IPv6 implementation where the nexthop is not properly released upon device removal. This can cause aperiodic hangups or kernel panics during network device removal, as observed in the pmtu.sh self-test. The issue arises from the fib6_info structure not being cleaned up correctly when disconnecting a device from a live IPv6 destination cache. The vulnerability does not impact confidentiality or integrity but can cause availability issues due to kernel hangs or crashes.
