CVE-2026-98404

A flaw was found in the Linux kernel's VirtIO GPU driver. A local user could exploit this flaw to cause a Denial of Service DoS by triggering a system crash. When user framebuffer creation encounters an error, the driver improperly returns a null value instead of an error code, resulting in a nul...

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...
