CVE-2018-11506

Estado: ModificadaAlta (7.8)—

La función sr_do_ioctl en drivers/scsi/sr_ioctl.c en el kernel de Linux hasta 4.16.12 permite a los usuarios locales causar una denegación de servicio (desbordamiento de búfer basado en pila) o, posiblemente, provocar otro impacto no especificado debido a que los búferes de sentido tienen diferentes tamaños en la capa de CDROM y en la capa SCSI, tal y como queda demostrado con una llamada ioctl CDROMREADMODE2.

CVSS

Probabilidad de explotación (EPSS)
