Name of the Vulnerable Software and Affected Versions Linux kernel versions 3.10.x through 3.16.x

Description The issue is related to a backport in the TCP Fast Open implementation for the Linux kernel. It does not properly maintain a count value, allowing local users to cause a denial of service, resulting in a system crash, via the Fast Open feature. This can be demonstrated by visiting the "chrome://flags/#enable-tcp-fast-open" URL when using certain kernel builds.

Recommendations For Linux kernel versions 3.10.x through 3.16.x, consider disabling the TCP Fast Open feature as a temporary workaround until a patch is available. Restrict access to the Fast Open feature to minimize the risk of exploitation.
