Descriptions

In the Linux kernel 5.0.21, mounting a crafted btrfs filesystem image and performing some operations can cause slab-out-of-bounds write access in __btrfs_map_block in fs/btrfs/volumes.c, because a value of 1 for the number of data stripes is mishandled.

En el kernel de Linux versión 5.0.21, montar una imagen del sistema de archivos btrfs especialmente diseñada y realizar algunas operaciones puede causar un acceso de escritura fuera de límites en la función __btrfs_map_block en el archivo fs/btrfs/volumes.c, porque un valor de 1 para el número de franjas de datos es mal manejado.
