Descriptions

The blk_rq_map_user_iov function in block/blk-map.c in the Linux kernel before 2.6.37-rc7 allows local users to cause a denial of service (panic) via a zero-length I/O request in a device ioctl to a SCSI device, related to an unaligned map. NOTE: this vulnerability exists because of an incomplete fix for CVE-2010-4163.

La función blk_rq_map_user_iov en block/blk-map.c en el kernel Linux anterior a 2.6.37-rc7 permite a usuarios locales causar una denegación de servicio (panic) a través de una petición I/O de longitud cero en un dispositivo ioctl a un dispositivo SCSI, relacionado con un mapa no alineado. NOTA: esta vulnerabilidad existe debido a una solución incompleta para CVE-2010-4163.
