Description Prasad Pandit 2013-06-06 09:12:03 UTC

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.

Upstream fix:

Comment 1 Prasad Pandit 2013-06-06 09:15:14 UTC

Statement:

This issue does not affect the version of the kernel package as shipped with

This issue affects the versions of Linux kernel as shipped with
Red Hat Enterprise Linux 6 and Red Hat Enterprise MRG 2. Future kernel updates
for Red Hat Enterprise Linux 6 and Red Hat Enterprise MRG 2 may address this
issue.
