The CVE-2023–32233 identifier has been reserved for the vulnerability, but a severity level is yet to be determined.
The security problem stems from Netfilter nf_tables accepting invalid updates to its configuration, allowing specific scenarios where invalid batch requests lead to the corruption of the subsystem’s internal state.
