In the Linux kernel, the following vulnerability has been resolved: dmaengine: dw-edma-pcie: Reject devices without driver data dw_edma_pcie_probe() treats the PCI device ID driver_data 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.
