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.

CVE-2015-5707 [MEDIUM] Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the kernel.
It was discovered that an integer overflow error existed in the SCSI
generic (sg) driver in the Linux kernel. A local attacker with write
permission to a SCSI generic device could use this to cause a denial of
service (system crash) or potentially escalate their privileges.
(CVE-2015-5707)
Marc-André Lureau discovered that the vhost driver did not properly
release the userspace provided log file descriptor. A privileged attacker
could use this to cause a denial of service (resource exhaustion).
(CVE-2015-6252)
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. (CVE-2015-6526)

CVE-2015-6526 [MEDIUM] CWE-835 kernel: perf on ppc64 can loop forever getting userlevel stacktraces
kernel: perf on ppc64 can loop forever getting userlevel stacktraces
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.
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.
Statement: This issue does not affect the Linux kernels as shipped with Red Hat Enterprise Linux 5, 6 and Red Hat Enterprise MRG 2.
