This issue was patched in ELSA-2023-3723.

NVD Description

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

In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch requests can be abused to perform arbitrary read and write operations on kernel memory. Unprivileged local users can obtain root privileges. This occurs because anonymous sets are mishandled.
