How to fix?

Upgrade Centos:9 kernel-zfcpdump-core to version 0:5.14.0-284.30.1.el9_2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-zfcpdump-core package and not the kernel-zfcpdump-core package as distributed by Centos. See How to fix? for Centos:9 relevant fixed versions and status.

A use-after-free vulnerability was found in the Linux kernel's netfilter subsystem in net/netfilter/nf_tables_api.c.

Mishandled error handling with NFT_MSG_NEWRULE makes it possible to use a dangling pointer in the same transaction causing a use-after-free vulnerability. This flaw allows a local attacker with user access to cause a privilege escalation issue.

We recommend upgrading past commit 1240eb93f0616b21c675416516ff3d74798fdc97.
