Descriptions

The bcm_connect function in net/can/bcm.c (aka the Broadcast Manager) in the Controller Area Network (CAN) implementation in the Linux kernel 2.6.36 and earlier creates a publicly accessible file with a filename containing a kernel memory address, which allows local users to obtain potentially sensitive information about kernel memory use by listing this filename.

La función bcm_connect en net/can/bcm.c (también conocido como el Broadcast Manager) en la implementación del Controller Area Network en el kernel de Linux 2.6.36 y anteriores crea un archivo público accesible con un nombre que contiene una dirección de memoria del kernel, lo que permite a usuarios locales obtener información sensible sobre el uso de memoria del kernel listado por este nombre de archivo.
