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.(CVE-2026-3195)\n\nAn integer overflow vulnerability was found in the virtio-snd device via PCM_INFO requests from the guest. A malicious guest can provide out-of-bounds stream counts, potentially leading to unbounded memory allocation on the host and a denial of service condition.(CVE-2026-3196)","affected":[{"package":{"ecosystem":"openEuler:24.03-LTS-SP1","name":"qemu","purl":"pkg:rpm/openEuler/qemu&distro=openEuler-24.03-LTS-SP1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.2.0-54.oe2403sp1"}]}],"ecosystem_specific":{"aarch64":["qemu-8.2.0-54.oe2403sp1.aarch64.rpm","qemu-block-curl-8.2.0-54.oe2403sp1.aarch64.rpm","qemu-block-iscsi-8.2.0-54.oe2403sp1.aarch64.rpm","qemu-block-rbd-8.2.0-54.oe2403sp1.aarch64.rpm","qemu-block-ssh-8.2.0-54.oe2403sp1.aarch64.rpm","qemu-debuginfo-8.2.0-54.oe2403sp1.aarch64.rpm","qemu-debugsource-8.2.0-54.oe2403sp1.aarch64.rpm","qemu-guest-agent-8.2.0-54.oe2403sp1.aarch64.rpm","qemu-hw-usb-host-8.2.0-54.oe2403sp1.aarch64.rpm","qemu-img-8.2.0-54.oe2403sp1.aarch64.rpm","qemu-system-aarch64-8.2.0-54.oe2403sp1.aarch64.rpm","qemu-system-arm-8.2.0-54.oe2403sp1.aarch64.rpm","qemu-system-riscv-8.2.0-54.oe2403sp1.aarch64.rpm","qemu-system-x86_64-8.2.0-54.oe2403sp1.aarch64.rpm","qemu-user-8.2.0-54.oe2403sp1.aarch64.rpm","qemu-user-binfmt-8.2.0-54.oe2403sp1.aarch64.rpm","qemu-user-static-8.2.0-54.oe2403sp1.aarch64.rpm"],"noarch":["qemu-help-8.2.0-54.oe2403sp1.noarch.rpm"],"src":["qemu-8.2.0-54.oe2403sp1.src.rpm"],"x86_64":["qemu-8.2.0-54.oe2403sp1.x86_64.rpm","qemu-block-curl-8.2.0-54.oe2403sp1.x86_64.rpm","qemu-block-iscsi-8.2.0-54.oe2403sp1.x86_64.rpm","qemu-block-rbd-8.2.0-54.oe2403sp1.x86_64.rpm","qemu-block-ssh-8.2.0-54.oe2403sp1.x86_64.rpm","qemu-debuginfo-8.2.0-54.oe2403sp1.x86_64.rpm","qemu-debugsource-8.2.0-54.oe2403sp1.x86_64.rpm","qemu-guest-agent-8.2.0-54.oe2403sp1.x86_64.rpm","qemu-hw-usb-host-8.2.0-54.oe2403sp1.x86_64.rpm","qemu-img-8.2.0-54.oe2403sp1.x86_64.rpm","qemu-seabios-8.2.0-54.oe2403sp1.x86_64.rpm","qemu-system-aarch64-8.2.0-54.oe2403sp1.x86_64.rpm","qemu-system-arm-8.2.0-54.oe2403sp1.x86_64.rpm","qemu-system-riscv-8.2.0-54.oe2403sp1.x86_64.rpm","qemu-system-x86_64-8.2.0-54.oe2403sp1.x86_64.rpm","qemu-user-8.2.0-54.oe2403sp1.x86_64.rpm","qemu-user-binfmt-8.2.0-54.oe2403sp1.x86_64.rpm","qemu-user-static-8.2.0-54.oe2403sp1.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-1846"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-3195"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-3196"}],"database_specific":{"severity":"High"}}
