{"url":"http://public2.vulnerablecode.io/api/vulnerabilities/77639?format=json","vulnerability_id":"VCID-abee-kgjm-h7gv","summary":"A flaw was found in libvirt in the virConnectListAllNodeDevices API in versions before 7.0.0. It only affects hosts with a PCI device and driver that supports mediated devices (e.g., GRID driver). This flaw could be used by an unprivileged client with a read-only connection to crash the libvirt daemon by executing the 'nodedev-list' virsh command. The highest threat from this vulnerability is to system availability.","aliases":[{"alias":"CVE-2021-3559"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/104215?format=json","purl":"pkg:deb/debian/libvirt@0?distro=trixie","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/libvirt@0%3Fdistro=trixie"},{"url":"http://public2.vulnerablecode.io/api/packages/104191?format=json","purl":"pkg:deb/debian/libvirt@7.0.0-3%2Bdeb11u3?distro=trixie","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-gt15-erjf-tucj"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/libvirt@7.0.0-3%252Bdeb11u3%3Fdistro=trixie"},{"url":"http://public2.vulnerablecode.io/api/packages/104189?format=json","purl":"pkg:deb/debian/libvirt@9.0.0-4%2Bdeb12u2?distro=trixie","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-gt15-erjf-tucj"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/libvirt@9.0.0-4%252Bdeb12u2%3Fdistro=trixie"},{"url":"http://public2.vulnerablecode.io/api/packages/104193?format=json","purl":"pkg:deb/debian/libvirt@11.3.0-3%2Bdeb13u2?distro=trixie","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/libvirt@11.3.0-3%252Bdeb13u2%3Fdistro=trixie"},{"url":"http://public2.vulnerablecode.io/api/packages/104192?format=json","purl":"pkg:deb/debian/libvirt@12.3.0-1?distro=trixie","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/libvirt@12.3.0-1%3Fdistro=trixie"}],"affected_packages":[],"references":[{"reference_url":"https://access.redhat.com/hydra/rest/securitydata/cve/CVE-2021-3559.json","reference_id":"","reference_type":"","scores":[{"value":"6.5","scoring_system":"cvssv3","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}],"url":"https://access.redhat.com/hydra/rest/securitydata/cve/CVE-2021-3559.json"},{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2021-3559","reference_id":"","reference_type":"","scores":[{"value":"0.00368","scoring_system":"epss","scoring_elements":"0.5902","published_at":"2026-06-04T12:55:00Z"},{"value":"0.00368","scoring_system":"epss","scoring_elements":"0.59068","published_at":"2026-06-05T12:55:00Z"},{"value":"0.00368","scoring_system":"epss","scoring_elements":"0.59073","published_at":"2026-06-06T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2021-3559"},{"reference_url":"https://ftp.suse.com/pub/projects/security/yaml/suse-cvss-scores.yaml","reference_id":"","reference_type":"","scores":[{"value":"6.5","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}],"url":"https://ftp.suse.com/pub/projects/security/yaml/suse-cvss-scores.yaml"},{"reference_url":"https://bugzilla.redhat.com/show_bug.cgi?id=1962306","reference_id":"1962306","reference_type":"","scores":[],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=1962306"}],"weaknesses":[{"cwe_id":119,"name":"Improper Restriction of Operations within the Bounds of a Memory Buffer","description":"The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer."}],"exploits":[],"severity_range_score":"6.5 - 6.5","exploitability":null,"weighted_severity":null,"risk_score":null,"resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-abee-kgjm-h7gv"}
