In the Linux kernel, the following vulnerability has been resolved:

netfilter: nf_tables: discard table flag update with pending basechain deletion

hook updates triggered by the table dormant flag. When both commands are
combined, this results in deleting a basechain while leaving its hook
still registered in the core.
