Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to an unbalanced DMA map/unmap for non-paged SKB data in the Linux kernel. This occurs when the non-paged data of a SKB carries protocol header and protocol payload to be transmitted on a certain platform with a specific DMA AXI address width configuration. The problem arises when the DMA engine does not finish pending descriptors, leading to access of unmapped memory regions, corrupted data transmission, or iommu faults. The patch corrects the DMA map/unmap sequences by fixing the array index for
tx q->tx skbuff dma[entry].buf when assigning the DMA buffer address.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
