Astra Linux – vulnerability in linux-6.1

In the Linux kernel, the following vulnerability has been resolved: netfilter: ctnetlink: ensure safe access to master conntrack Holding a reference to the master conntrack object is insufficient; it can simply disappear, rendering exp-master invalid. To safely access exp-master: - Grab the...

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,...
