Descriptions
In the Linux kernel, the following vulnerability has been resolved: driver core: platform: use generic driver_override infrastructure When a driver is probed through __driver_attach(), the bus' match()
callback is called without the device lock held, thus accessing the
driver_override field without a lock, which can cause a UAF. Fix this by using the driver-core driver_override infrastructure taking
care of proper locking internally. Note that calling match() from __driver_attach() without the device lock
held is intentional. [1]
