On multi-user systems with a permissive umask, other local users could read or modify the temporary directory used while installing apps or runtimes, potentially causing installation failures (denial of service); tampered content would fail signature/digest verification rather than being trusted.","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-2026-97026","source_modified_at":"2026-09-30T20:11:11.704Z","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-2026-97026","source_modified_at":"2026-09-30T20:11:11.704Z","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-2026-97026","source_modified_at":"2026-09-30T20:11:11.704Z","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-2026-97026","source_modified_at":"2026-09-30T20:11:11.704Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Red Hat Enterprise Linux 9","vendor":"Red Hat","versions":[],"defaultStatus":"affected"}],"fixed_versions":[],"cvss":3.9,"severity":"Low","kev":{"listed":false},"epss":{"probability":0.00108,"percentile":0.01152,"score_date":"2026-10-23"},"published_at":"2026-09-28T20:57:03.702Z","modified_at":"2026-09-30T20:11:11.704Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-97026","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-30T20:11:11.704Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-97026","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-2026-97026","tags":["vdb-entry","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2542637","tags":["issue-tracking","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://github.com/flatpak/flatpak/security/advisories/GHSA-r9w3-qx54-qvc8"}],"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":"2026-09-30T19:42:12.533797Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-09-30T20:11:11.704Z","content_hash":"6f53aa367a4fcc07d14a00908803cfdefebc79103ccc4905b5cdec85fd04126f"}}
