The legacy nfsd4_decode_nfstime4 has this check but the TIME_DELEG paths do not. A malformed timespec can propagate through notify_change() to disk.</p> <p>Add range checks in both nfs4xdr.c (SETATTR path) and nfs4callback.c (CB_GETATTR path).</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>nfsd: validate nseconds in TIME_DELEG decode paths</p> <p>The xdrgen-based TIME_DELEG_ACCESS and TIME_DELEG_MODIFY decode arms store a raw uint32_t nseconds directly into tv_nsec without enforcing nseconds &lt; NSEC_PER_SEC.
