Description: | The media_device_enum_entities function in drivers/media/media-device.c in the Linux kernel before 3.14.6 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel memory by leveraging /dev/media0 read access for a MEDIA_IOC_ENUM_ENTITIES ioctl call. Salva Peiró discovered an information leak in the Linux kernel's media- device driver. A local attacker could exploit this flaw to obtain sensitive information from kernel memory.
