{"id":"DEBIAN-CVE-2024-3446","details":"A double free vulnerability was found in QEMU virtio devices (virtio-gpu, virtio-serial-bus, virtio-crypto), where the mem_reentrancy_guard flag insufficiently protects against DMA reentrancy issues. This issue could allow a malicious privileged guest user to crash the QEMU process on the host, resulting in a denial of service or allow arbitrary code execution within the context of the QEMU process on the host.","modified":"2026-09-15T09:03:08.338252736Z","published":"2024-04-09T20:15:10.450Z","upstream":["CVE-2024-3446"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2024-3446"}],"affected":[{"package":{"name":"qemu","ecosystem":"Debian:12","purl":"pkg:deb/debian/qemu?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:7.2+dfsg-7+deb12u6"}]}],"versions":["1:7.2+dfsg-7","1:7.2+dfsg-7+deb12u1","1:7.2+dfsg-7+deb12u2","1:7.2+dfsg-7+deb12u2~bpo11+1","1:7.2+dfsg-7+deb12u3","1:7.2+dfsg-7+deb12u4","1:7.2+dfsg-7+deb12u5"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-3446.json"}},{"package":{"name":"qemu","ecosystem":"Debian:13","purl":"pkg:deb/debian/qemu?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:8.2.3+ds-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-3446.json"}},{"package":{"name":"qemu","ecosystem":"Debian:14","purl":"pkg:deb/debian/qemu?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:8.2.3+ds-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-3446.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H"}]}
