Description:
A vulnerability has been reported in NetBSD, which can be exploited by malicious, local users to cause a DoS (Denial of Service).
The vulnerability is caused due to a division by zero error in certain audio drivers when processing an "ioctl()" call that contains both the "unpaused" command and the block-size change information.
Successful exploitation crashes the kernel, but requires access to the audio device.
The vulnerability has been reported in the "clcs" and "emuxki" drivers for the Cirrus Logic CS4280/CS4281, SB Live!, and SB PC 512 hardware.
