Details

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

NFSD: Initialize struct nfsd4_copy earlier

Ensure the refcount and async_copies fields are initialized early. cleanup_async_copy() will reference these fields if an error occurs in nfsd4_copy(). If they are not correctly initialized, at the very least, a refcount underflow occurs.
