In the Linux kernel, the following vulnerability has been resolved:
nfsd: check nfsd4_acl_to_attr() return value in nfsd4_create()
nfsd4_create() stores the return value of nfsd4_acl_to_attr() in
status, but the switch(create->cr_type) block unconditionally
overwrites it in every branch. ACL translation errors are silently
discarded, and the CREATE proceeds without the requested ACL.
Add an early exit check after nfsd4_acl_to_attr(), matching the
pattern already used in nfsd4_setattr().
[ cel: prefer NFS4ERR_BADTYPE over NFS4ERR_ATTRNOTSUPP ]
