"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: erofs: se corrige el acceso fuera de los l\u00edmites cuando z_erofs_gbuf_growsize() falla parcialmente Si z_erofs_gbuf_growsize() falla parcialmente en un b\u00fafer global debido a un error en la asignaci\u00f3n de memoria o inyecci\u00f3n de fallas (como lo inform\u00f3 syzbot [1]), se deben liberar nuevas p\u00e1ginas compar\u00e1ndolas con las p\u00e1ginas existentes para evitar fugas de memoria. Sin embargo, la matriz gbuf->pages[] anterior puede no ser lo suficientemente grande, lo que puede provocar un acceso fuera de los l\u00edmites o una desreferencia de ptr nula. Corrija esto verificando con gbuf->nrpages de antemano. [1] https://lore.kernel.org/r/000000000000f7b96e062018c6e3@google.com"
