NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek-devel package and not the kernel-uek-devel package as distributed by Oracle. See How to fix? for Oracle:7 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

netfilter: ipset: Fix suspicious rcu_dereference_protected()

When destroying all sets, we are either in pernet exit phase or are executing a "destroy all sets command" from userspace. The latter was taken into account in ip_set_dereference() (nfnetlink mutex is held), but the former was not. The patch adds the required check to rcu_dereference_protected() in ip_set_dereference().
