Descriptions

Race condition in kernel/events/core.c in the Linux kernel before 4.9.7 allows local users to gain privileges via a crafted application that makes concurrent perf_event_open system calls for moving a software group into a hardware context. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-6786.

Condición de carrera en kernel/events/core.c en el kernel de Linux en versiones anteriores a 4.9.7 permite a usuarios locales obtener privilegios a través de una aplicación manipulada que hace llamadas concurrentes al sistema perf_event_open para mover un grupo de software en un contexto hardware. NOTA: esta vulnerabilidad existe debido a una solución incompleta para CVE-2016-6786.

It was found that the original fix for CVE-2016-6786 was incomplete. There exist a race between two concurrent sys_perf_event_open() calls when both try and move the same pre-existing software group into a hardware context.
