- s390/cio: use generic driver_override infrastructure
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
s390/cio: use generic driver_override infrastructure
When a driver is probed through __driverattach(), the bus' match() callback is called without the device lock held, thus accessing the driveroverride 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 _driverattach() without the device lock held is intentional. [1]
