Descriptions

arch/x86/entry/entry_64.S in the Linux kernel before 4.1.6 on the x86_64 platform improperly relies on espfix64 during nested NMI processing, which allows local users to gain privileges by triggering an NMI within a certain instruction window.

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, confía indebidamente en espfix64 durante el procesamiento anidado de NMI, lo que permite a usuarios locales obtener privilegios al desencadenar una NMI dentro de una cierta ventana de instrucción.

Privilege escalation can occur in Linux due to nested NMIs interrupting espfix64.
