{"id":"ALPINE-CVE-2021-3409","details":"The patch for CVE-2020-17380/CVE-2020-25085 was found to be ineffective, thus making QEMU vulnerable to the out-of-bounds read/write access issues previously found in the SDHCI controller emulation code. This flaw allows a malicious privileged guest to crash the QEMU process on the host, resulting in a denial of service or potential code execution. QEMU up to (including) 5.2.0 is affected by this.","modified":"2026-11-03T06:32:58.491472015Z","published":"2021-03-23T21:15:14.697Z","upstream":["CVE-2021-3409"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2021-3409"}],"affected":[{"package":{"name":"qemu","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/qemu?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.0.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-3409.json"}},{"package":{"name":"qemu","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/qemu?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.0.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-3409.json"}},{"package":{"name":"qemu","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/qemu?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.0.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-3409.json"}},{"package":{"name":"qemu","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/qemu?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.0.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-3409.json"}},{"package":{"name":"qemu","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/qemu?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.0.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-3409.json"}},{"package":{"name":"qemu","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/qemu?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.0.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-3409.json"}},{"package":{"name":"qemu","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/qemu?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.0.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-3409.json"}},{"package":{"name":"qemu","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/qemu?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.0.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-3409.json"}},{"package":{"name":"qemu","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/qemu?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.0.0-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-3409.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:L"}]}
