"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnfsd: validate nseconds in TIME_DELEG decode paths\n\nThe xdrgen-based TIME_DELEG_ACCESS and TIME_DELEG_MODIFY decode arms\nstore a raw uint32_t nseconds directly into tv_nsec without enforcing\nnseconds < NSEC_PER_SEC. The legacy nfsd4_decode_nfstime4 has this\ncheck but the TIME_DELEG paths do not. A malformed timespec can\npropagate through notify_change() to disk.\n\nAdd range checks in both nfs4xdr.c (SETATTR path) and\nnfs4callback.c (CB_GETATTR path)."
