CVE ID:	CVE-2024-35900
Description:	In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: reject new basechain after table flag update When dormant flag is toggled, hooks are disabled in the commit phase by iterating over current chains in table (existing and new). The following configuration allows for an inconsistent state: add table x add chain x y { type filter hook input priority 0; } add table x { flags dormant; } add chain x w { type filter hook input priority 1; } which triggers the following warning when trying to unregister chain w which is already unregistered.
