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.","categories":["Operating systems"],"product":"Red Hat Enterprise Linux 10","vendor":"Red Hat","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97027","source_modified_at":"2026-09-29T19:40:02.638Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Red Hat Enterprise Linux 10","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97027","source_modified_at":"2026-09-29T19:40:02.638Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Red Hat Enterprise Linux 7","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97027","source_modified_at":"2026-09-29T19:40:02.638Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Red Hat Enterprise Linux 8","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97027","source_modified_at":"2026-09-29T19:40:02.638Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Red Hat Enterprise Linux 9","vendor":"Red Hat","versions":[],"defaultStatus":"affected"}],"fixed_versions":[],"cvss":3.6,"severity":"Low","kev":{"listed":false},"epss":{"probability":0.00128,"percentile":0.02204,"score_date":"2026-10-23"},"published_at":"2026-09-28T20:57:06.758Z","modified_at":"2026-09-29T19:40:02.638Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-97027","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-29T19:40:02.638Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-97027","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://access.redhat.com/security/cve/CVE-2026-97027","tags":["vdb-entry","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2542683","tags":["issue-tracking","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://github.com/flatpak/flatpak/security/advisories/GHSA-v64f-hrwr-j4vh"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-09-29T19:39:47.160409Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-09-29T19:40:02.638Z","content_hash":"bddef3abe0eae37f058c3f5d8ee8bfe157c94781e31e617b23eed04b1da1d9dd"}}
