A vulnerability in the Linux kernel's netfs subsystem was resolved involving incorrect update of the zero point when local file size (i_size) exceeds the remote server file size (remote_i_size). The zero point indicates the file position beyond which reads can be assumed to return zeros without accessing the server. The flaw caused zero_point to be updated based on the local i_size rather than the remote_i_size, potentially leading to incorrect read behavior. This was fixed by limiting zero_point to remote_i_size. The issue was identified through extensive filesystem testing (xfstest) on CIFS with default caching.
