It occurs when dropping packets during a bulk transfer from a SPICE client due to the packet queue being full. A malicious SPICE client could use this flaw to make QEMU call free() with faked heap chunk metadata, resulting in a crash of QEMU or potential code execution with the privileges of the QEMU process on the host.",null,[],[],[],[14],{"_key":15},"CVE-2021-3682",[17,19],{"_key":18},"USN-5307-1",{"_key":20},"USN-5772-1",[],[23,24],{"_key":18},{"_key":20},"2021-08-05T20:15:00Z","2026-02-04T03:56:52.035232Z",{"cisa_kev":28,"cisa_ransomware":28,"cisa_vendor":9,"epss_severity":9,"epss_score":9,"severity":9,"severity_score":9,"severity_version":9,"severity_source":9,"severity_vector":9,"severity_status":9},false,[30,36,41,45],{"url":31,"sources":32,"tags":34},"https://ubuntu.com/security/CVE-2021-3682",[33],"osv_ubuntu",[35],"REPORT",{"url":37,"sources":38,"tags":39},"https://ubuntu.com/security/notices/USN-5307-1",[33],[40],"Advisory",{"url":42,"sources":43,"tags":44},"https://ubuntu.com/security/notices/USN-5772-1",[33],[40],{"url":46,"sources":47,"tags":48},"https://www.cve.org/CVERecord?id=CVE-2021-3682",[33],[35],[],[],[52],{"source":33,"cvss_v2_0":9,"cvss_v3_0":9,"cvss_v3_1":53,"cvss_v4_0":9},{"baseScore":54,"baseSeverity":9,"vectorString":55,"impactScore":56,"exploitabilityScore":57},8.5,"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H",10,4.6,[59],{"ecosystem":60,"name":61,"vendor":62,"product":61,"cpe_part":9,"purl_type":63,"purl_namespace":62,"purl_name":61,"source":9,"versions":64},"Ubuntu","qemu","ubuntu","deb",[65,71,74,77,80],{"version":66,"is_range":67,"range_type":68,"version_start":9,"version_start_type":9,"version_end":69,"version_end_type":70,"fixed_in":9},"lt2_0_0+dfsg_2ubuntu1_47+esm2",true,"ecosystem","2.0.0+dfsg-2ubuntu1.47+esm2","excluding",{"version":72,"is_range":67,"range_type":68,"version_start":9,"version_start_type":9,"version_end":73,"version_end_type":70,"fixed_in":9},"lt1:2_5+dfsg_5ubuntu10_51+esm1","1:2.5+dfsg-5ubuntu10.51+esm1",{"version":75,"is_range":67,"range_type":68,"version_start":9,"version_start_type":9,"version_end":76,"version_end_type":70,"fixed_in":9},"lt1:2_11+dfsg_1ubuntu7_39","1:2.11+dfsg-1ubuntu7.39",{"version":78,"is_range":67,"range_type":68,"version_start":9,"version_start_type":9,"version_end":79,"version_end_type":70,"fixed_in":9},"lt1:4_2_3ubuntu6_21","1:4.2-3ubuntu6.21",{"version":81,"is_range":67,"range_type":68,"version_start":9,"version_start_type":9,"version_end":82,"version_end_type":70,"fixed_in":9},"lt1:6_2+dfsg_2ubuntu5","1:6.2+dfsg-2ubuntu5"]
