CVE-2017-0861

Published: 16 November 2017

Use-after-free vulnerability in the snd_pcm_info function in the ALSA subsystem in the Linux kernel allows attackers to gain privileges via unspecified vectors.

From the Ubuntu Security Team

It was discovered that a race condition leading to a use-after-free vulnerability existed in the ALSA PCM subsystem of the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
