In the Linux kernel, the following vulnerability has been resolved:
Drivers: hv: vmbus: 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]
