Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> netdev: prevent accessing NAPI instances from another namespace<br /> <br /> The NAPI IDs were not fully exposed to user space prior to the netlink<br /> API, so they were never namespaced. The netlink API must ensure that<br /> at the very least NAPI instance belongs to the same netns as the owner<br /> of the genl sock.<br /> <br /> napi_by_id() can become static now, but it needs to move because of<br /> dev_get_by_napi_id().
