Description Prasad Pandit 2013-08-20 09:34:20 UTC 
Linux kernel built for the ARM(CONFIG_ARM/CONFIG_ARM64) platforms along with the
hardware performance counter support(CONFIG_HW_PERF_EVENTS) is vulnerable to a
NULL pointer dereference flaw. This could lead to the kernel crash resulting in
DoS or potential privilege escalation to gain root privileges by a non-root user.

An unprivileged user/program could use this flaw to crash the kernel resulting
in DoS or potential privilege escalation to gain root access to a machine.
