Descriptions

arch/x86/entry/entry_64.S in the Linux kernel before 4.1.6 on the x86_64 platform does not properly determine when nested NMI processing is occurring, which allows local users to cause a denial of service (skipped NMI) by modifying the rsp register, issuing a syscall instruction, and triggering an NMI.

Vulnerabilidad en arch/x86/entry/entry_64.S en el kernel de Linux en versiones anteriores a 4.1.6 en la plataforma x86_64, no determina correctamente cuándo está ocurriendo el procesamiento anidado de NMI, lo que permite a usuarios locales causar una denegación de servicio (NMI saltada) modificando el registro rsp, causando una llamada de instrucción del sistema y desencadenando una NMI.
