CVE-2026-3195: Heap-based Buffer OverflowCVE-2026-3195 0 CVE-2026-3195 is a heap-based buffer overflow vulnerability in QEMU's virtio-snd device input callback function, virtio_snd_pcm_in_cb. The flaw arises from insufficient validation of input audio data buffer sizes, potentially leading to out-of-bounds heap writes. This vulnerability is a result of an incomplete fix for a previous issue (CVE-2024-7730). It affects multiple Ubuntu package versions and is rated with a high severity CVSS score of 7.4. The vulnerability could allow an attacker inside a guest virtual machine to cause a denial of service or possibly execute arbitrary code on the host. Red Hat's QEMU packages are not affected due to the virtio-snd device being disabled at build time. Official patches are available from Ubuntu, and system updates followed by QEMU virtual machine restarts are required to remediate the issue.
