Race condition in the snd_pcm_period_elapsed function in sound/core/pcm_lib.c in the ALSA subsystem in the Linux kernel before 4.7 allows local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via a crafted SNDRV_PCM_TRIGGER_START command.

Security readout for executives and security teams

CVE-2016-9794 is an old Linux kernel ALSA audio subsystem flaw. A local user could trigger a race condition that may crash the system through a use-after-free condition. The provided sources do not show active exploitation or a remote attack path. Exposure is most plausible on systems running Linux kernels before 4.7, or vendor kernels lacking the relevant ALSA backport, where local users or local code can access PCM audio interfaces. The source bundle also includes Android and Linux distribution advisories. Schedule remediation through normal kernel maintenance, escalating for shared or unmanaged endpoints. The issue is old and local-only in the provided evidence, but kernel crashes can affect availability and operational reliability. Mitigation focus: Apply vendor kernel updates that include the ALSA race-condition fix.; Confirm distro or Android vendor advisories cover CVE-2016-9794 for deployed builds.; Prioritize shared, multi-user, kiosk, and device fleets running old kernels..
