"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: erofs/zmap.c: Se corrigi\u00f3 el c\u00e1lculo incorrecto del desplazamiento. El desplazamiento efectivo para a\u00f1adir a length se calculaba incorrectamente, lo que provocaba que iomap->length se estableciera en 0, lo que activaba un WARN_ON en iomap_iter_done(). Se corrigi\u00f3 y se describi\u00f3 en los comentarios. syzbot report\u00f3 esto como un fallo en un problema relacionado con una advertencia encontrada en iomap_iter_done(), pero no relacionada con erofs.
