Описание
A NULL pointer dereference flaw was found in the az6027 driver in drivers/media/usb/dev-usb/az6027.c in the Linux Kernel. The message from user space is not checked properly before transferring into the device. This flaw allows a local user to crash the system or potentially cause a denial of service.
Отчет
This flaw can be mitigated by preventing the affected dvb_usb_az6027 kernel module from loading during the boot time. Ensure the module is added into the blacklist file.
