1218454: CVE-2015-6526 kernel: perf on ppc64 can loop forever getting userlevel stacktraces
A flaw was found in the way the Linux kernel's perf subsystem retrieved userlevel stack traces on PowerPC systems. A local, unprivileged user could use this flaw to cause a denial of service on the system by creating a special stack layout that would force the perf_callchain_user_64() function into an infinite loop.
