CVE-2026-3195
Published:June 19, 2026
Updated:August 06, 2026
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.
