## Description
In the Linux kernel, the following vulnerability has been resolved:
nstree: check listing permission before taking a namespace reference
legitimize\_ns() takes a reference on the candidate namespace before
may\_list\_ns() has decided whether the caller may see it. The
\_\_free(ns\_put) cleanup on the denied path can drop the last reference to a
mount namespace while we still hold the rcu read lock, and put\_mnt\_ns()
may sleep there. This is the same problem commit 2ec2aff3c8e2 ("ns: make
sure reference are dropped outside of rcu lock") fixed for the put\_user()
path. Neither ns\_requested() nor may\_list\_ns() needs a reference, both
only look at the namespace type and at the caller's own namespaces, so do
the checks first and take the reference last.
Splat:
Voluntary context switch within RCU read-side critical section!
