Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 5.2.8

Description The issue is related to a NULL pointer dereference in the sound/usb/helper.c (motu microbookii) driver of the Linux kernel. This can be caused by a malicious USB device. Exploitation of this issue may allow an attacker to cause a denial of service.

Recommendations For Linux kernel versions prior to 5.2.8, update to version 5.2.8 or later to resolve the issue. As a temporary workaround, consider disabling the use of USB devices that may trigger this issue until a patch is applied.
