AV:L/AC:L/Au:N/C:N/I:N/A:P

Name of the Vulnerable Software and Affected Versions: NetBSD versions 1.6 through 2.0.2

Description: The issue allows local users to cause a denial of service, resulting in a kernel crash. This is achieved by using the set-parameters ioctl on an audio device to change the block size and set the pause state to "unpaused" in the same ioctl, which causes a divide-by-zero error.

Recommendations: For NetBSD versions 1.6 through 2.0.2, consider disabling the set-parameters ioctl on audio devices as a temporary workaround until a patch is available. Restrict access to the clcs and emuxki drivers to minimize the risk of exploitation. Avoid using the set-parameters ioctl to change the block size and pause state simultaneously on audio devices until the issue is resolved.
