Summary
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 (TM) instructions in the core dump path, leading to a denial of service.

Esto se debe a la falta de verificaci\u00f3n de la funcionalidad del procesador y un uso err\u00f3neo de las instrucciones de la memoria transaccional (TM) en la ruta de volcado de memoria, lo que da lugar a una denegaci\u00f3n de servicio (DoS)."
