CVE-2024-35900 is a flaw in the Linux kernel netfilter nf_tables subsystem. When a table's dormant flag is toggled, the commit path disables hooks by iterating both existing and newly created chains. nf_tables previously permitted creation of a new base chain after the table flag update within the same transaction, producing an inconsistent hook-registration state. Later removal or unregistration of that chain attempts to unregister a hook that is already unregistered, triggering a kernel warning in the netfilter hook-unregistration path. The upstream fix rejects new base chains after the relevant table flag update.
