CVE-2026-53115
bus: fsl-mc: use generic driver_override infrastructure
Description
In the Linux kernel, the following vulnerability has been resolved: bus: fsl-mc: 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]

Solution
- Update the Linux kernel to include the driver_override fix.
- Ensure the bus driver uses the driver_override infrastructure.
- Verify that the device lock protects driver_override access.
