CVE-2024-56751

A flaw was found in the IPv6 implementation of the Linux kernel. When a network device is removed, the kernel fails to properly release associated nexthop references in certain cases. This can lead to stale references being held in the routing infrastructure, causing hangs or delays during device teardown. A local attacker could exploit this condition to cause denial of service during device removal, impacting system availability.

For triggering requires privileges. The security impact is limited.
