NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek-modules-extra package and not the kernel-uek-modules-extra package as distributed by Oracle. See How to fix? for Oracle:8 relevant fixed versions and status.

A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation.

Addition and removal of rules from chain bindings within the same transaction causes leads to use-after-free.

We recommend upgrading past commit f15f29fd4779be8a418b66e9d52979bb6d6c2325.
