Описание

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

nsfs: tighten permission checks for ns iteration ioctls

Even privileged services should not necessarily be able to see other privileged service's namespaces so they can't leak information to each other. Use may_see_all_namespaces() helper that centralizes this policy until the nstree adapts.
