CVE-2011-1012

Estado: ModificadaMedia (4.9)—

La función ldm_parse_vmdb en fs/partitions/ldm.c en el kernel de Linux anterior a v2.6.38-rc6-git6, no valida el valor del tamaño VBLK en la estructura VMDB en una tabla de particiones LDM, lo que permite a usuarios locales causar una denegación de servicio (división por cero error y OOPS) a través de una tabla de particiones manipulada.
