NVD Description

Note: Versions mentioned in the description apply only to the upstream linux-virt-doc package and not the linux-virt-doc package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

netdev: prevent accessing NAPI instances from another namespace

The NAPI IDs were not fully exposed to user space prior to the netlink API, so they were never namespaced. The netlink API must ensure that at the very least NAPI instance belongs to the same netns as the owner of the genl sock.

napi_by_id() can become static now, but it needs to move because of dev_get_by_napi_id().
