Description
A flaw was found in the Linux kernel's Network File System daemon (nfsd). When configuring file exports through the Netlink interface, nfsd attempts to initialize parallel NFS (pNFS) layouts without verifying that pNFS is enabled for the export. A privileged local user managing NFS exports could trigger this condition, potentially leading to improper export configuration and unexpected system behavior or a Denial of Service (DoS).
