CVE-2025-39808

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

Description The Linux kernel contains a flaw within the ntrig report version() function related to handling page faults. Specifically, a null pointer dereference can occur when accessing hdev->dev.parent->parent after sending a descriptor to /dev/uhid. This can lead to a page fault error when usb rcvctrlpipe() is called with an invalid address. The issue arises from a missing null check before calling hid to usb dev().

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