  "details" : [ "A use-after-free flaw was found in the Linux kernel’s sound subsystem in the way a user triggers concurrent calls of PCM hw_params. The hw_free ioctls or similar race condition happens inside ALSA PCM for other ioctls. This flaw allows a local user to crash or potentially escalate their privileges on the system.", "A use-after-free flaw was found in the Linux kernel’s sound subsystem in the way a user triggers concurrent calls of PCM hw_params.

  "statement" : "Keeping the rating as Moderate, because this issue is hard to trigger and requires some permissions for accessing the sound card and only exists if a specific model of the sound card such as Intel 82801 or similar. The known reproducer works only for systems where the /dev/snd/pcmC0D1c device exists.",
