A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

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.
