CVE-2011-4611 (retired)

Priority
Description
Integer overflow in the perf_event_interrupt function in
arch/powerpc/kernel/perf_event.c in the Linux kernel before 2.6.39 on
powerpc platforms allows local users to cause a denial of service
(unhandled performance monitor exception) via vectors that trigger certain
outcomes of performance events.
Ubuntu-Description
Maynard Johnson discovered that on POWER7, certain speculative events may
raise a performance monitor exception. A local attacker could exploit this
to crash the system, leading to a denial of service.

 apw> arm branches can express the issue and so are not-affected
