Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A use-after-free (UAF) issue exists in the logitech-hidpp module during the probing of the Logitech G920 Driving Force Racing Wheel for Xbox One. If force feedback initialisation fails, an error is returned before the userspace infrastructure, specifically sysfs and /dev/input, is torn down. If userspace ignores these errors and continues to use references to these dangling entities, a UAF occurs. Use-after-free is a condition where a program continues to use a pointer after it has been freed, which can lead to crashes or arbitrary code execution.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
