Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 5.1.8

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

Recommendations For Linux kernel versions prior to 5.1.8, update to version 5.1.8 or later to resolve the issue. As a temporary workaround, consider disabling the use of USB devices from untrusted sources to minimize the risk of exploitation. Restrict access to the sisusb.c driver to minimize the risk of denial of service.
