CVE-2026-64159

CVE-2026-64159 is a bug in the Linux kernel's netfs (network file system) library. The function netfs_release_folio() incorrectly uses the local i_size instead of remote_i_size when updating the zero point (the file position from which the server is assumed to return zeros). This occurs when unco...
