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

Description A flaw exists in the Linux kernel related to HID devices and uclogic handling. Specifically, an incorrect device reference for devm allocation of the input device name could lead to a use-after-free condition. This occurs when the input device is unregistered and a uevent is triggered that relies on the freed name. The issue is addressed by referencing the HID device instead of the input device for the devm allocation and by using devm kasprintf to simplify memory allocation and string formatting for the input device name.

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