CVE-2024-27065 affects the Linux kernel netfilter nf_tables subsystem's table-update handling. The vulnerable logic compares internal table flags when processing table updates, preventing a transaction from being skipped even when the externally requested table flags have not changed. The fix excludes internal table flags from this comparison and restores skipping of no-op table-update transactions.
