In the Linux kernel, the following vulnerability has been resolved:
dmaengine: dw-edma-pcie: Reject devices without driver data
dwedmapcieprobe() treats the PCI device ID driverdata as the template for the controller layout and copies it unconditionally. A device bound dynamically via sysfs can match the driver without that data, which leads to a NULL pointer dereference.
Reject such matches before enabling the device.
