Descriptions

arch/x86/entry/entry_64.S in the Linux kernel before 4.1.6 on the x86_64 platform mishandles IRET faults in processing NMIs that occurred during userspace execution, which might allow local users to gain privileges by 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 maneja correctamente los fallos IRET procesando NMIs que ocurrieron durante la ejecución en el espacio de usuario, lo que puede permitir a usuarios locales obtener privilegios mediante desencadenamiento de una NMI.

A flaw was found in the way the Linux kernel handled IRET faults during the processing of NMIs. An unprivileged, local user could use this flaw to crash the system or, potentially (although highly unlikely), escalate their privileges on the system.
