Description
In the Linux kernel, the following vulnerability has been resolved: HID: hid-ntrig: fix unable to handle page fault in ntrig_report_version() in ntrig_report_version(), hdev parameter passed from hid_probe(). sending descriptor to /dev/uhid can make hdev->dev.parent->parent to null if hdev->dev.parent->parent is null, usb_dev has invalid address(0xffffffffffffff58) that hid_to_usb_dev(hdev) returned when usb_rcvctrlpipe() use usb_dev,it trigger page fault error for address(0xffffffffffffff58) add null check logic to ntrig_report_version() before calling hid_to_usb_dev()

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability occurs in the Linux kernel's HID ntrig driver, specifically in the function ntrig_report_version(). When a descriptor is sent to /dev/uhid, it can cause a parameter (hdev->dev.parent->parent) to become null. This leads to an invalid address being returned by hid_to_usb_dev(hdev). When usb_rcvctrlpipe() uses this invalid address, it triggers a page fault error. The issue was fixed by adding a null check before calling hid_to_usb_dev().


How can this vulnerability impact me? :

This vulnerability can cause a page fault error in the Linux kernel, potentially leading to a system crash or instability when the affected HID driver processes certain inputs. This could disrupt normal device operation or system functionality.
