{"schema":"threatline.record/2","record":{"id":"CVE-2026-89088","aliases":[],"summary":"Parted: parted: denial of service via heap buffer overflow during fat16 resize","details":"A flaw was found in parted. A heap-based buffer overflow exists in libparted's file system resizing logic when handling FAT16 volumes. By convincing a user or administrator to resize a specially crafted FAT16 file system image with malformed directory metadata, an attacker can trigger an oversized read into a fixed-size memory buffer. This issue causes memory corruption, resulting in an application crash and a denial of service (DoS).","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-2026-89088","source_modified_at":"2026-10-19T15:04:58.470Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Red Hat Enterprise Linux 10","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-89088","source_modified_at":"2026-10-19T15:04:58.470Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Red Hat Enterprise Linux 6","vendor":"Red Hat","versions":[],"defaultStatus":"unknown"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-89088","source_modified_at":"2026-10-19T15:04:58.470Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Red Hat Enterprise Linux 7","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-89088","source_modified_at":"2026-10-19T15:04:58.470Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Red Hat Enterprise Linux 8","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-89088","source_modified_at":"2026-10-19T15:04:58.470Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Red Hat Enterprise Linux 9","vendor":"Red Hat","versions":[],"defaultStatus":"affected"}],"fixed_versions":[],"cvss":5.5,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00117,"percentile":0.01562,"score_date":"2026-10-23"},"published_at":"2026-10-16T23:06:18.907Z","modified_at":"2026-10-19T15:04:58.470Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-89088","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T15:04:58.470Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-89088","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-2026-89088","tags":["vdb-entry","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2462951","tags":["exploit"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-19T15:04:52.411004Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-19T15:04:58.470Z","content_hash":"596677da44b99a3613248753274914d28aa18e0c630748ff008aa33329516203"}}
