{"id":"ALPINE-CVE-2021-3713","details":"An out-of-bounds write flaw was found in the UAS (USB Attached SCSI) device emulation of QEMU in versions prior to 6.2.0-rc0. The device uses the guest supplied stream number unchecked, which can lead to out-of-bounds access to the UASDevice-\u003edata3 and UASDevice-\u003estatus3 fields. A malicious guest user could use this flaw to crash QEMU or potentially achieve code execution with the privileges of the QEMU process on the host.","modified":"2026-11-03T06:32:39.333344107Z","published":"2021-08-25T19:15:15.073Z","upstream":["CVE-2021-3713"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2021-3713"}],"affected":[{"package":{"name":"qemu","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/qemu?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.1-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-3713.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:P/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"}]}
