Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A NULL pointer dereference occurs in the cdns3 driver when a role switch to host mode happens during the system resume process. The start() operation of the host role registers a xhci-hcd device, but the probe is deferred during the resume path. Because the resume() operation incorrectly assumes the xhci-hcd device has already been probed, it leads to a memory access violation. This issue is triggered within the cdns host resume() and usb hcd is primary hcd() functions.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
