Descriptions
A security flaw was found in the Linux kernel in a way that the cleancache subsystem clears an inode after the final file truncation (removal). The new file created with the same inode may contain leftover pages from cleancache and the old file data instead of the new one.
Se ha detectado un fallo de seguridad en el kernel de Linux de manera que el subsistema "cleancache" borre un inode después del truncado de archivos final (eliminación). El nuevo archivo creado con el mismo inode podría contener páginas restantes del "cleancache" y los datos antiguos del mismo, en vez de los del nuevo archivo.
