Description

In the Linux kernel, the following vulnerability has been resolved: usb: core: Prevent null pointer dereference in update_port_device_state Currently, the function update_port_device_state gets the usb_hub from udev->parent by calling usb_hub_to_struct_hub. However, in case the actconfig or the maxchild is 0, the usb_hub would be NULL and upon further accessing to get port_dev would result in null pointer dereference. Fix this by introducing an if check after the usb_hub is populated.

Affected configurations

• linux linux kernel (>= 6.5 < 6.6.18) • linux linux kernel (>= 6.7 < 6.7.6) • linux linux kernel 6.8
