Vulnerability Description

In the Linux kernel, the following vulnerability has been resolved: dmaengine: dw-edma: HDMA: Add sync read before starting the DMA transfer in remote setup The Linked list element and pointer are not stored in the same memory as the HDMA controller register.

In remote setup we can only use a readl to the memory to assure the full write has occurred.
