How to fix?

NVD Description

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

In PolicyKit (aka polkit) 0.115, the "start time" protection mechanism can be bypassed because fork() is not atomic, and therefore authorization decisions are improperly cached. This is related to lack of uid checking in polkitbackend/polkitbackendinteractiveauthority.c.
