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

NFSv4: Fix incorrect argument passed to nfs4_delete_lease() in nfs4_add_lease()

When nfs4_add_lease() races with a delegation return, it calls
nfs4_delete_lease() to clean up. Previously, it passed priv,
which can legitimately be NULL. Passing a NULL priv eventually
leads to a NULL pointer dereference in generic_setlease().
