CVE-2026-89706

A vulnerability in the Linux kernel's nfsd (NFS server) component causes silent data loss during asynchronous COPY operations. When post-copy writeback fails (via vfs_fsync_range() or filemap_check_wb_err()), the server correctly reports NFS_UNSTABLE but fails to rotate the write verifier. The cl...
