Описание
An issue was discovered in the Linux kernel before 5.2.3. There is a NULL pointer dereference caused by a malicious USB device in the drivers/media/usb/zr364xx/zr364xx.c driver.
A vulnerability was found in the Linux kernel. The Zr364xx USB device driver is susceptible to malicious USB devices. An attacker able to add a specific USB device could cause a crash leading to a denial of service.
Меры по смягчению последствий
To mitigate this issue, prevent module zr364xx from being loaded. Please see https://access.redhat.com/solutions/41278 for how to blacklist a kernel module to prevent it from loading automatically.
