Descriptions

The snd_msnd_interrupt function in sound/isa/msnd/msnd_pinnacle.c in the Linux kernel through 4.11.7 allows local users to cause a denial of service (over-boundary access) or possibly have unspecified other impact by changing the value of a message queue head pointer between two kernel reads of that value, aka a "double fetch" vulnerability.

La función snd_msnd_interrupt en el archivo sound/isa/msnd/msnd_pinnacle.c en el kernel de Linux hasta la versión 4.11.7 permite a los usuarios locales causar una denegación de servicio (acceso por encima del limite) u otro posible impacto no especificado mediante el cambio del valor del puntero a la cabeza de la cola de mensajes entre la lectura de dicho valor de los dos kernels, también conocido como vulnerabilidad "double fetch".
