This issue occurs when flushing TX in the virtio_net_flush_tx function if guest features VIRTIO_NET_F_HASH_REPORT, VIRTIO_F_VERSION_1 and VIRTIO_NET_F_MRG_RXBUF are enabled. This could allow a malicious user to overwrite local variables allocated on the stack. Specifically, the `out_sg` variable could be used to read a part of process memory and send it to the wire, causing an information leak.",null,[],[],[],[14],{"_key":15},"CVE-2023-6693",[17],{"_key":18},"USN-6954-1",[],[21],{"_key":18},"2024-01-02T10:15:00Z","2026-02-04T02:23:19.169507Z",{"cisa_kev":25,"cisa_ransomware":25,"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,[27,33,37,41,45],{"url":28,"sources":29,"tags":31},"https://ubuntu.com/security/CVE-2023-6693",[30],"osv_ubuntu",[32],"REPORT",{"url":34,"sources":35,"tags":36},"https://access.redhat.com/security/cve/CVE-2023-6693",[30],[32],{"url":38,"sources":39,"tags":40},"https://lists.nongnu.org/archive/html/qemu-devel/2024-01/msg00045.html",[30],[32],{"url":42,"sources":43,"tags":44},"https://www.cve.org/CVERecord?id=CVE-2023-6693",[30],[32],{"url":46,"sources":47,"tags":48},"https://ubuntu.com/security/notices/USN-6954-1",[30],[49],"Advisory",[],[],[53],{"source":30,"cvss_v2_0":9,"cvss_v3_0":9,"cvss_v3_1":54,"cvss_v4_0":9},{"baseScore":55,"baseSeverity":9,"vectorString":56,"impactScore":57,"exploitabilityScore":58},4.9,"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L",5.7,3.6,[60],{"ecosystem":61,"name":62,"vendor":63,"product":62,"cpe_part":9,"purl_type":64,"purl_namespace":63,"purl_name":62,"source":9,"versions":65},"Ubuntu","qemu","ubuntu","deb",[66],{"version":67,"is_range":68,"range_type":69,"version_start":9,"version_start_type":9,"version_end":70,"version_end_type":71,"fixed_in":9},"lt1:6_2+dfsg_2ubuntu6_22",true,"ecosystem","1:6.2+dfsg-2ubuntu6.22","excluding"]
