{"schema":"threatline.record/2","record":{"id":"CVE-2026-92446","aliases":["GHSA-m779-jvp3-pmqr"],"summary":"GUIX binary resource loader reads past the end of a resource, because no length for it ever reaches the loader","details":"`gx_binres_theme_load()` and `gx_binres_font_load()` take the resource as a bare `GX_UBYTE *` with no length, and `GX_BINRES_DATA_INFO` has no field to carry one. Every read is therefore performed at an offset the file itself chose, against a buffer whose extent the loader does not know. A resource that declares more data than it contains is read past its end, and an offset stored in the file is turned into a pointer without being bounded.\n\n\n\nThis is a distinct defect from GHSA-hgcj-22cg-4hfv, which was an underflowed glyph count. It needs no underflow and no wrapped multiply: a perfectly well-formed, narrow glyph range reaches it.","categories":["Unclassified"],"product":"Eclipse ThreadX - GUIX","vendor":"Eclipse Foundation","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-92446","source_modified_at":"2026-10-20T15:26:36.082Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Eclipse ThreadX - GUIX","vendor":"Eclipse Foundation","versions":[{"status":"affected","version":"0","lessThanOrEqual":"6.5.1.202602a","versionType":"semver"},{"status":"unaffected","version":"6.5.2.202603"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6.8,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00159,"percentile":0.04637,"score_date":"2026-10-23"},"published_at":"2026-10-20T14:52:45.765Z","modified_at":"2026-10-20T15:26:36.082Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-92446","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-20T15:26:36.082Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-92446","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/eclipse-threadx/guix/security/advisories/GHSA-m779-jvp3-pmqr"}],"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":"2026-10-20T15:26:01.270098Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-20T15:26:36.082Z","content_hash":"5bdb538eeb67be46e37353d164db077f730bc63d91a4b7e18d295c4bfe6c7761"}}
