1563994: CVE-2017-0861 kernel: Use-after-free in snd_pcm_info function in ALSA subsystem potentially leads to privilege escalation
Use-after-free vulnerability in the snd_pcm_info() function in the ALSA subsystem in the Linux kernel allows attackers to induce a kernel memory corruption and possibly crash or lock up a system. Due to the nature of the flaw, a privilege escalation cannot be fully ruled out, although we believe it is unlikely.
