Description OSIDB Bzimport 2026-08-15 06:24:22 UTC
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.
