{"schema":"threatline.record/2","record":{"id":"CVE-2026-96280","aliases":["GHSA-jr92-2v97-wgvc"],"summary":"Flatpak: flatpak: buffer overflow in oci delta stream path names on 32-bit systems","details":"The OCI delta stream parser read sizes as guint64 but passed them to GLib I/O and allocation functions expecting gsize (32 bits on 32-bit systems), causing undersized allocations while subsequent operations use the original 64-bit size, leading to heap buffer overflows. An attacker controlling an OCI registry can craft a delta stream that triggers this during flatpak install/update, potentially achieving code execution on 32-bit systems.","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-2026-96280","source_modified_at":"2026-10-12T16:25:45.209Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Red Hat Enterprise Linux 10","vendor":"Red Hat","versions":[{"version":"0:1.16.0-9.el10_2.4","lessThan":"*","versionType":"rpm","status":"unaffected"}],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-96280","source_modified_at":"2026-10-12T16:25:45.209Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Red Hat Enterprise Linux 8","vendor":"Red Hat","versions":[{"version":"0:1.12.9-7.el8_10","lessThan":"*","versionType":"rpm","status":"unaffected"}],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-96280","source_modified_at":"2026-10-12T16:25:45.209Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Red Hat Enterprise Linux 9","vendor":"Red Hat","versions":[{"version":"0:1.12.9-4.el9_8.4","lessThan":"*","versionType":"rpm","status":"unaffected"}],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-96280","source_modified_at":"2026-10-12T16:25:45.209Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Red Hat Enterprise Linux 7","vendor":"Red Hat","versions":[],"defaultStatus":"affected"}],"fixed_versions":[],"cvss":7.5,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00665,"percentile":0.51223,"score_date":"2026-10-23"},"published_at":"2026-09-27T20:19:12.890Z","modified_at":"2026-10-12T16:25:45.209Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-96280","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-12T16:25:45.209Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-96280","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/errata/RHSA-2026:80497","tags":["vendor-advisory","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://access.redhat.com/errata/RHSA-2026:80498","tags":["vendor-advisory","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://access.redhat.com/errata/RHSA-2026:80687","tags":["vendor-advisory","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://access.redhat.com/security/cve/CVE-2026-96280","tags":["vdb-entry","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2539419","tags":["issue-tracking","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://github.com/flatpak/flatpak/security/advisories/GHSA-jr92-2v97-wgvc"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-09-29T15:50:48.098460Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-12T16:25:45.209Z","content_hash":"1cee20784857bfe9ee72aa1f7ff576d07b2e6b4fbb728a2d9565e8225710aabc"}}
