In the Linux kernel, the following vulnerability has been resolved:

nfsd: fix nfsd_file leak on inter-server COPY setup failure

When nfsd4_setup_inter_ssc() fails, nfsd4_copy() returns

nfserr_offload_denied directly, bypassing the out: label where

release_copy_files() would drop the nf_dst reference taken by

nfs4_preprocess_stateid_op(). Each failed inter-server COPY

leaks one nfsd_file, pinning file/inode/dentry/vfsmount.

Fix by setting status and jumping to out: instead of returning

directly. (NVD)
