Linux is "a clone of the UNIX operating system, written from scratch by Linus Torvalds with assistance from a loosely-knit team of hackers across the Internet. The Advanced Linux Sound Architecture (ALSA) project provides audio device support for Linux systems". Local exploitation of an information disclosure vulnerability within the ALSA driver included in the Linux Kernel allows attackers to obtain sensitive information from kernel memory.
