Descriptions

Race condition in the ioctl_send_fib function in drivers/scsi/aacraid/commctrl.c in the Linux kernel through 4.7 allows local users to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value, aka a "double fetch" vulnerability.

Condición de carrera en la función ioctl_send_fib en drivers/scsi/aacraid/commctrl.c en el kernel de Linux hasta la versión 4.7 permite a usuarios locales provocar una denegación de servicio (acceso fuera de rango o caída de sistema) cambiando un cierto valor de tamaño, también conocido como una vulnerabilidad de "doble recuperación".

A race condition flaw was found in the ioctl_send_fib() function in the Linux kernel's aacraid implementation. A local attacker could use this flaw to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value.
