  "details": "In the Linux kernel, the following vulnerability has been resolved:  nfsd: validate nseconds in TIME_DELEG decode paths  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 \u003c NSEC_PER_SEC. 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.  Add range checks in both nfs4xdr.c (SETATTR path) and nfs4callback.c (CB_GETATTR path).",
