Ubuntu.comUB:CVE-2021-47260CVE-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.
