Description
CVE-2024-27065 is a high-severity vulnerability in the Linux kernel's netfilter nf_tables component. The flaw involved improper comparison of internal table flags during updates, which could lead to incorrect transaction skipping. This issue has been resolved by restoring the skipping of transactions only if the table update does not modify flags.
