NVD Description

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

An integer overflow flaw was found in the Linux kernel. This issue leads to the kernel allocating skb_shared_info in the userspace, which is exploitable in systems without SMAP protection since skb_shared_info contains references to function pointers.
