CVE-2015-6526 (retired)

Priority
Description
The perf_callchain_user_64 function in arch/powerpc/perf/callchain.c in the
Linux kernel before 4.0.2 on ppc64 platforms allows local users to cause a
denial of service (infinite loop) via a deep 64-bit userspace backtrace.
Ubuntu-Description
It was discovered that the Linux kernel's perf subsystem did not bound
callchain backtraces on PowerPC 64. A local attacker could use this to
cause a denial of service.
