CVE-2026-3195 is a high-severity vulnerability rated 7.4/10 on the CVSS scale. 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. EPSS estimates a 0.13% chance of exploitation in the next 30 days.
