CyberRota Analysis
AI-GeneratedThe vulnerability in the Linux kernel affects the dw-edma-pcie driver, where improper handling of PCI device IDs can lead to a NULL pointer dereference if a device is bound dynamically without the necessary driver data. This flaw could result in system crashes or instability when the device is enabled. Organizations utilizing Linux systems with this driver should prioritize patching to mitigate potential disruptions in service.
Original NVD Description
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.
