CVE-2026-53000 is a high-severity vulnerability in the Linux kernel netfilter NAT subsystem. It involves improper release of netfilter hook operations, which could lead to use-after-free conditions. The issue was addressed by changing the release method to use kfree_rcu to defer freeing safely. This fix prevents potential memory corruption or crashes related to netfilter hooks. The vulnerability affects Linux kernel versions prior to the patched release. Red Hat has issued an important security advisory with a kernel update that resolves this issue. Systems must be rebooted after applying the update to ensure the fix takes effect.
