- Description
- A heap buffer overflow was found in the virtio-snd device in QEMU. When reading input audio in the virtio-snd input callback, virtio_snd_pcm_in_cb, the function did not check whether the iov can fit the data buffer. This issue can trigger an out-of-bounds write if the size of the virtio queue element is equal to virtio_snd_pcm_status, which makes the available space for audio data zero.

An AI agent found that QEMU's patch for CVE-2024-7730 was incomplete — it missed edge cases in the same function (virtio_snd_pcm_in_cb). The remaining heap overflow is CVE-2026-3195. Disclosed 3 months after the AI reported it. QEMU maintainers accepted the report.
