  "details": "In the Linux kernel, the following vulnerability has been resolved:  NFSD: Fix SECINFO_NO_NAME decode error cleanup  nfsd4_decode_secinfo_no_name() currently initializes sin_exp after decoding sin_style. If the XDR stream is truncated, the decoder returns nfserr_bad_xdr before sin_exp is initialized.  Since commit 3fdc54646234 (\"NFSD: Reduce amount of struct nfsd4_compoundargs that needs clearing\"), the inline iops array is not cleared between RPC calls. A failed SECINFO_NO_NAME decode can therefore leave sin_exp holding stale union contents from a previous operation.  The error response path still invokes nfsd4_secinfo_no_name_release(), which calls exp_put() on a non-NULL sin_exp.  Initialize sin_exp before the first failable decode step, matching nfsd4_decode_secinfo().",
