Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 5.2.3

Description The issue is related to a NULL pointer dereference in the drivers/media/usb/zr364xx/zr364xx.c driver, caused by a malicious USB device. This can lead to a denial of service.

Recommendations For Linux kernel versions prior to 5.2.3, update to version 5.2.3 or later to resolve the issue. As a temporary workaround, consider disabling the use of the zr364xx driver until a patch is available. Restrict access to USB devices to minimize the risk of exploitation.
