Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> vhost_task: Handle SIGKILL by flushing work and exiting<br /> <br /> Instead of lingering until the device is closed, this has us handle<br /> SIGKILL by:<br /> <br /> 1. marking the worker as killed so we no longer try to use it with<br /> new virtqueues and new flush operations.<br /> 2. setting the virtqueue to worker mapping so no new works are queued.<br /> 3. running all the exiting works.
