Details
In the Linux kernel, the following vulnerability has been resolved:
usb: roles: fix NULL pointer issue when put module's reference
In current design, usb role class driver will get usb_role_switch parent's
module reference after the user get usb_role_switch device and put the
reference after the user put the usb_role_switch device. However, the
parent device of usb_role_switch may be removed before the user put the
usb_role_switch. If so, then, NULL pointer issue will be met when the user
put the parent module's reference.
This will save the module pointer in structure of usb_role_switch. Then,
we don't need to find module by iterating long relations.
