Vulnerability details

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to improper input validation within the vhost_task_fn(), EXPORT_SYMBOL_GPL() and vhost_task_create() functions in kernel/vhost_task.c, within the __vhost_worker_flush(), vhost_vq_reset(), vhost_worker(), vhost_worker_create(), __vhost_vq_attach_worker() and vhost_free_worker() functions in drivers/vhost/vhost.c. A local user can perform a denial of service (DoS) attack.
