A malicious Flatpak app can use this to cause denial of service (e.g. forced application restart loops) or to influence host D-Bus/systemd activation behavior beyond what the sandbox is intended to permit.","evidence":"cve:CVE-2026-97027","products":[{"name":{"value":"Red Hat Enterprise Linux 10","evidence":"/containers/cna/affected/0/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]},{"name":{"value":"Red Hat Enterprise Linux 7","evidence":"/containers/cna/affected/1/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]},{"name":{"value":"Red Hat Enterprise Linux 8","evidence":"/containers/cna/affected/2/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]},{"name":{"value":"Red Hat Enterprise Linux 9","evidence":"/containers/cna/affected/3/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]}],"severity":"low","structured":{"id":"CVE-2026-97027","aliases":["CVE-2026-97027"],"metrics":[{"other":{"type":"Red Hat severity rating","content":{"value":"Low","namespace":"https://access.redhat.com/security/updates/classification/"}}},{"format":"CVSS","cvssV3_1":{"scope":"CHANGED","version":"3.1","baseScore":3.6,"attackVector":"LOCAL","baseSeverity":"LOW","vectorString":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:N/I:N/A:L","integrityImpact":"NONE","userInteraction":"REQUIRED","attackComplexity":"LOW","availabilityImpact":"LOW","privilegesRequired":"NONE","confidentialityImpact":"NONE"}}],"affected":[{"cpes":["cpe:/o:redhat:enterprise_linux:10"],"vendor":"Red Hat","product":"Red Hat Enterprise Linux 10","packageName":"flatpak","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","defaultStatus":"affected"},{"cpes":["cpe:/o:redhat:enterprise_linux:7"],"vendor":"Red Hat","product":"Red Hat Enterprise Linux 7","packageName":"flatpak","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","defaultStatus":"affected"},{"cpes":["cpe:/o:redhat:enterprise_linux:8"],"vendor":"Red Hat","product":"Red Hat Enterprise Linux 8","packageName":"flatpak","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","defaultStatus":"affected"},{"cpes":["cpe:/o:redhat:enterprise_linux:9"],"vendor":"Red Hat","product":"Red Hat Enterprise Linux 9","packageName":"flatpak","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","defaultStatus":"affected"}],"modified":"2026-09-29T19:40:02.638Z","provider":"cve","references":["https://access.redhat.com/security/cve/CVE-2026-97027","https://bugzilla.redhat.com/show_bug.cgi?id=2542683","https://github.com/flatpak/flatpak/security/advisories/GHSA-v64f-hrwr-j4vh"],"provider_metadata":{"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-97027","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-09-29T19:39:47.160409Z"}}}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-29T19:40:02.638Z"}}],"cna":{"orgId":"53f830b8-0a3f-465b-8143-3b8a9948e749","shortName":"redhat","dateUpdated":"2026-09-28T20:57:06.758Z"}}},"related_cves":[{"value":"CVE-2026-97027","evidence":"/cveMetadata/cveId"}],"security_relevant":true,"severity_evidence":"/containers/cna/metrics"}}],"next_after":3989,"next_before":3989}
