Descriptions
The ext4_zero_range function in fs/ext4/extents.c in the Linux kernel before 4.1 allows local users to cause a denial of service (BUG) via a crafted fallocate zero-range request.
La función ext4_zero_range en fs/ext4/extents.c en el kernel de Linux en versiones anteriores a 4.1 permite a usuarios locales provocar una denegación de servicio (BUG) a través de una petición de rango cero a fallocate manipulada.
A flaw was found in the way the Linux kernel's ext4 file system handled the "page size > block size" condition when the fallocate zero range functionality was used. A local attacker could use this flaw to crash the system.
