{"id":"UBUNTU-CVE-2026-57965","details":"A flaw was found in spice-vdagent. A malicious or compromised SPICE host can trigger an integer overflow by sending a specially crafted message. This vulnerability can lead to a heap buffer overflow, causing the spice-vdagent daemon to crash and resulting in a Denial of Service (DoS) for the virtual machine. This issue requires the SPICE host to be untrusted or compromised for exploitation.","modified":"2026-09-03T22:52:55.247083361Z","published":"2026-06-29T09:16:00Z","related":["USN-8723-1"],"upstream":["CVE-2026-57965"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-57965"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-57965"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2026-57965"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-8723-1"}],"affected":[{"package":{"name":"spice-vdagent","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/spice-vdagent?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.15.0-1.3"],"ecosystem_specific":{"binaries":[{"binary_name":"spice-vdagent","binary_version":"0.15.0-1.3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-57965.json"}},{"package":{"name":"spice-vdagent","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/spice-vdagent?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.17.0-1ubuntu1","0.17.0-1ubuntu2","0.17.0-1ubuntu2.2"],"ecosystem_specific":{"binaries":[{"binary_version":"0.17.0-1ubuntu2.2","binary_name":"spice-vdagent"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-57965.json"}},{"package":{"name":"spice-vdagent","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/spice-vdagent?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.19.0-2","0.19.0-2ubuntu0.2"],"ecosystem_specific":{"binaries":[{"binary_name":"spice-vdagent","binary_version":"0.19.0-2ubuntu0.2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-57965.json"}},{"package":{"name":"spice-vdagent","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/spice-vdagent?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.22.1-1ubuntu0.1"}]}],"versions":["0.20.0-2build1","0.20.0-3","0.22.1-1"],"ecosystem_specific":{"binaries":[{"binary_name":"spice-vdagent","binary_version":"0.22.1-1ubuntu0.1"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-57965.json"}},{"package":{"name":"spice-vdagent","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/spice-vdagent?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.22.1-4ubuntu0.1"}]}],"versions":["0.22.1-3","0.22.1-4","0.22.1-4build1","0.22.1-4build2","0.22.1-4build3"],"ecosystem_specific":{"binaries":[{"binary_name":"spice-vdagent","binary_version":"0.22.1-4ubuntu0.1"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-57965.json"}},{"package":{"name":"spice-vdagent","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/spice-vdagent?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.22.1-4.1","0.22.1-4.1ubuntu1","0.22.1-5"],"ecosystem_specific":{"binaries":[{"binary_name":"spice-vdagent","binary_version":"0.22.1-5"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-57965.json"}},{"package":{"name":"spice-vdagent","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/spice-vdagent?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.23.0-1ubuntu0.1"}]}],"versions":["0.22.1-5","0.23.0-1"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_version":"0.23.0-1ubuntu0.1","binary_name":"spice-vdagent"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-57965.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:H"},{"type":"Ubuntu","score":"medium"}]}
