In the Linux kernel, the following vulnerability has been resolved: usb: cdns3: fix role switching during resume If the role change while we are suspended, the cdns3 driver switches to the new mode during resume. However, switching to host mode in this context causes a NULL pointer dereference. The host role's start() operation registers a xhci-hcd device, but its probe is deferred while we are in the resume path. The host role's resume() operation assumes the xhci-hcd device is already probed, which is not the case, leading to the dereference. Since the start() operation of the new role is already called, the resume operation can be skipped. So skip the resume operation for the new role if a role switch occurs during resume. Once the resume sequence is complete, the xhci-hcd device can be probed in case of host mode. Unable to handle kernel NULL pointer dereference at virtual address 0000000000000208 Mem abort info: ...
