In the Linux kernel, the following vulnerability has been resolved:

PCI: use generic driveroverride 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 driveroverride infrastructure taking care of proper locking internally.

Note that calling match() from driverattach() without the device lock held is intentional. [1]

Remediation

Recommended actions to resolve this vulnerability, in priority order.

Compensating control
Use the driver-core driver_override infrastructure so access to the driver_override field handles proper locking internally.
