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...

kernel: drm/virtio: use uninterruptible resv lock for plane updates

A flaw was found in the Linux kernel's VirtIO GPU Graphics Processing Unit driver. The virtiogpucursorplaneupdate and virtiogpuresourceflush functions fail to properly acquire a required lock, which can lead to a race condition. A local user could exploit this vulnerability by triggering a memory...
