Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to the Linux kernel on arm64 architecture, specifically the Qualcomm sc7280 device tree. If the PCIe controller is not marked as cache coherent, the kernel may attempt to ensure coherency during DMA operations, potentially leading to data corruption. The fix involves marking the PCIe node as dma-coherent, as devices on the PCIe bus are cache coherent.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
