Description Agostino Sarubbo gentoo-dev 2013-06-07 09:37:19 UTC 
From ${URL} :

Linux kernel built with the Performance Events Subsystem(CONFIG_PERF_EVENTS=y)
is vulnerable to a kernel crash flaw, caused by incorrect masking of the
reserved bits.

A user/program could use this flaw to crash the kernel, resulting in DoS.
