CVE-2026-3195

CVE-2026-3195 · Qemu-kvm: virtio-snd: heap buffer overflow in virtio_snd_pcm_in_cb (incomplete fix for cve-2024-7730)

This page contains facts from public vulnerability sources. Check the original advisory before updating.

A flaw was found in QEMU. When reading input audio in the virtio-snd device input callback, the `virtio_snd_pcm_in_cb` function did not check whether the iov could fit the data buffer, potentially leading to a heap out-of-bounds write. This issue exists due to an incomplete fix for CVE-2024-7730.
