In the flush_tmregs_to_thread function in arch/powerpc/kernel/ptrace.c in
the Linux kernel before 4.13.5, a guest kernel crash can be triggered from
unprivileged userspace during a core dump on a POWER host due to a missing
processor feature check and an erroneous use of transactional memory ™
instructions in the core dump path, leading to a denial of service.
