Descriptions

The mbcache feature in the ext2 and ext4 filesystem implementations in the Linux kernel before 4.6 mishandles xattr block caching, which allows local users to cause a denial of service (soft lockup) via filesystem operations in environments that use many attributes, as demonstrated by Ceph and Samba.

La funcionalidad mbcache en las implementaciones del sistema de archivos ext2 y ext4 en el kernel de Linux en versiones anteriores a 4.6 no maneja adecuadamente bloque de almacenamiento en caché xattr, lo que permite a usuarios locales provocar una denegación de servicio (bloqueo débil) a través de operaciones de sistema de archivos en entornos que usan muchos atributos, como se demuestra por Ceph y Samba.
