NVD Description

Note: Versions mentioned in the description apply only to the upstream python-perf package and not the python-perf package as distributed by Centos.

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.
