In the Linux kernel, the following vulnerability has been resolved: nfsd: fix handling of NFSEXP_PNFS in the netlink codepath The rework of how block layouts were checked moved the check for NFSEXP_PNFS out of nfsd4_setup_layout_type() and into the callers. That patch didn't account for the new call in nfsd4_setup_layout_type().
