{"id":"DEBIAN-CVE-2024-3447","details":"A heap-based buffer overflow was found in the SDHCI device emulation of QEMU. The bug is triggered when both `s-\u003edata_count` and the size of  `s-\u003efifo_buffer` are set to 0x200, leading to an out-of-bound access. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition.","modified":"2026-09-15T09:03:13.765761127Z","published":"2024-11-14T12:15:17.743Z","upstream":["CVE-2024-3447"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2024-3447"}],"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-2024-3447.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-2024-3447.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-2024-3447.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:N/I:N/A:H"}]}
