CVE-2026-64098

CVE-2026-64098 affects the Linux kernel’s VirtIO GPU driver. The issue arises when virtio_gpu_cursor_plane_update() and virtio_gpu_resource_flush() acquire the framebuffer dma_resv via virtio_gpu_array_lock_resv() and ignore the return value. The lock can fail (-EINTR or -ENOMEM), leaving the res...
