kernel: netfilter: ctnetlink: ensure safe access to master conntrack

A flaw was found in the netfilter: ctnetlink component of the Linux kernel. This vulnerability occurs due to insufficient locking when accessing the master conntrack object, allowing it to become invalid while still being referenced. A local attacker could potentially exploit this race condition,...
