An update for qemu is now available for openEuler-24.03-LTS-SP3 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2026-1794 Final 1.0 1.0 2026-04-03 Initial 2026-04-03 2026-04-03 openEuler SA Tool V1.0 2026-04-03 qemu security update An update for qemu is now available for openEuler-24.03-LTS-SP3 QEMU is a FAST! processor emulator using dynamic translation to achieve good emulation speed. Security Fix(es): 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.(CVE-2026-3195) An 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) An update for qemu is now available for openEuler-24.03-LTS-SP3. openEuler Security has rated this update as having a security impact of high. A Common Vunlnerability Scoring System(CVSS)base score,which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.
