Описание
In the Linux kernel, the following vulnerability has been resolved:
drm/virtio: fix object leak in virtio_gpu_resource_create_ioctl()
virtio_gpu_resource_create_ioctl() calls drm_gem_object_release() on the
drm_gem_handle_create() error path instead of dropping the reference it
owns, so obj->funcs->free() never runs and the virtio_gpu_object, its
pages and sg table, the resource id and the host-side resource are
leaked.
Use drm_gem_object_put() instead.
A flaw was found in the Linux kernel's VirtIO GPU (graphics processing unit) driver. When handling resource creation requests, an improper error-handling path fails to release acquired object references upon failure, causing memory and system resources to leak. A local user could exploit this flaw by repeatedly triggering failed resource creation requests, leading to kernel resource exhaustion and a Denial of Service (DoS).
