Title
NFS: Fix a potential NULL dereference in nfs_get_client()
Summary
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.
Severity ?
No CVSS data available.
