{"id":"AZL-6831","summary":"CVE-2021-3713 affecting package qemu for versions less than 6.2.0-2","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":"2026-04-01T05:21:23.725384Z","published":"2021-08-25T19:15:15Z","upstream":["CVE-2021-3713"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-3713"}],"affected":[{"package":{"name":"qemu","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/qemu"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.2.0-2"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-6831.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:P/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"}]}
