CVE-2026-98156

The Linux kernel contains a vulnerability in the drm/virtio component when running on Xen . The root cause is that virtio-gpu independently determines whether to use the DMA API based solely on a feature bit. Because QEMU does not set iommu_platform on virtio-vga by default, the system fails to n...
