A flaw was found in the Linux kernel's IPv6 networking subsystem. A local attacker or network traffic triggering route exceptions while an IPv6 route is being removed can cause a circular reference leak. This failure to release resources prevents network devices from unregistering, resulting in stalled operations and a Denial of Service (DoS).
