A vulnerability in the Linux kernel's NFS server (nfsd) was fixed involving improper handling of write verifiers during asynchronous COPY writeback failures. When the async COPY writeback fails, the server did not rotate the write verifier, causing clients to mistakenly believe that data was durably written when it was not, violating the NFS protocol's durability guarantees.
