Description

A race condition issue was found in the way the raw packet socket implementation in the Linux kernel networking subsystem handled synchronization. A local user able to open a raw packet socket (requires the CAP_NET_RAW capability) could use this to waste resources in the kernel's ring buffer or possibly cause an out-of-bounds read on the heap leading to a system crash.

Statement

This issue affects the Linux kernel packages as shipped with Red Hat Enterprise Linux 6, 7, and MRG-2.

Future Linux kernel updates for the respective releases may address this issue.
