AI-suggested
Red Hat states that their qemu-kvm packages as shipped are not affected because the virtio-snd device is disabled at build-time, effectively removing the attack surface. Therefore, no action is required for Red Hat Enterprise Linux users. For other environments where virtio-snd is enabled, monitor vendor advisories for patches or mitigations.
Description
An integer overflow vulnerability was found in the virtio-snd device via PCM_INFO requests from the guest. A malicious guest can provide out-of-bounds stream counts, potentially leading to unbounded memory allocation on the host and a denial of service condition.
