{"id":"ALPINE-CVE-2022-2962","details":"A DMA reentrancy issue was found in the Tulip device emulation in QEMU. When Tulip reads or writes to the rx/tx descriptor or copies the rx/tx frame, it doesn't check whether the destination address is its own MMIO address. This can cause the device to trigger MMIO handlers multiple times, possibly leading to a stack or heap overflow. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition.","modified":"2026-11-03T07:30:20.367046546Z","published":"2022-09-13T20:15:09.640Z","upstream":["CVE-2022-2962"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2022-2962"}],"affected":[{"package":{"name":"qemu","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/qemu?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.2.0"},{"fixed":"7.1.0-r4"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-2962.json"}},{"package":{"name":"qemu","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/qemu?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.2.0"},{"fixed":"7.1.0-r4"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-2962.json"}},{"package":{"name":"qemu","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/qemu?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.2.0"},{"fixed":"7.1.0-r4"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-2962.json"}},{"package":{"name":"qemu","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/qemu?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.2.0"},{"fixed":"7.1.0-r4"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-2962.json"}},{"package":{"name":"qemu","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/qemu?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.2.0"},{"fixed":"7.1.0-r4"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-2962.json"}},{"package":{"name":"qemu","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/qemu?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.2.0"},{"fixed":"7.1.0-r4"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-2962.json"}},{"package":{"name":"qemu","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/qemu?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.2.0"},{"fixed":"7.1.0-r4"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-2962.json"}},{"package":{"name":"qemu","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/qemu?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.2.0"},{"fixed":"7.1.0-r4"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-2962.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
