If such an address is mapped without VM_MIXEDMAP, vm_insert_page() will trigger a BUG_ON due to the VM_PFNMAP restriction.</p> <p>Fix this by checking for vmalloc addresses and setting VM_MIXEDMAP in the VMA before mapping. This ensures safe mapping and avoids kernel crashes. The memory is still driver-allocated and cannot be accessed directly by userspace.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>accel/habanalabs: support mapping cb with vmalloc-backed coherent memory</p> <p>When IOMMU is enabled, dma_alloc_coherent() with GFP_USER may return addresses from the vmalloc range.
