Describe CVE-2021-47260.
What is CVE-2021-47260?
In the Linux kernel, the following vulnerability has been resolved:

NFS: Fix a potential NULL dereference in nfs_get_client()

None of the callers are expecting NULL returns from nfs_get_client() so
this code will lead to an Oops.  It's better to return an error
pointer.  I expect that this is dead code so hopefully no one is
affected..
