In the Linux kernel, the following vulnerability has been resolved:
netfilter: xt_CT: drop pending enqueued packets on template removal
Templates refer to objects that can go away while packets are sitting in nfqueue refer to:
- helper, this can be an issue on module removal. - timeout policy, nfnetlink_cttimeout might remove it.
The use of templates with zone and event cache filter are safe, since this just copies values.
Flush these enqueued packets in case the template rule gets removed.
