A truncated segment is therefore read past the end of the caller's image buffer. Separately, a zero chroma sampling factor makes the block decode loop non-terminating. Both reproduce in the default configuration, in which `GX_SOFTWARE_DECODER_SUPPORT` is enabled.","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-2026-92454","source_modified_at":"2026-10-20T15:21:42.800Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Eclipse ThreadX - GUIX","vendor":"Eclipse Foundation","versions":[{"lessThanOrEqual":"6.5.1.202602a","status":"affected","version":"0","versionType":"semver"},{"status":"unaffected","version":"6.5.2.202603"}],"defaultStatus":"unaffected"},{"source":"GitHub Advisory Database","source_url":"https://github.com/eclipse-threadx/guix/security/advisories/GHSA-pppm-h3g4-986x","source_modified_at":"2026-10-02T18:44:56Z","fetched_at":"2026-10-23T20:39:26.410340Z","package":{"ecosystem":"eclipse threadx","name":"GUIX"},"range":"<= 6.5.1.202602a"}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/eclipse-threadx/guix/security/advisories/GHSA-pppm-h3g4-986x","source_modified_at":"2026-10-02T18:44:56Z","fetched_at":"2026-10-23T20:39:26.410340Z","package":{"ecosystem":"eclipse threadx","name":"GUIX"},"version":"6.5.2.202603"}],"cvss":6.1,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00151,"percentile":0.03925,"score_date":"2026-10-23"},"published_at":"2026-10-20T14:58:36.821Z","modified_at":"2026-10-20T15:21:42.800Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-92454","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-20T15:21:42.800Z"},{"source":"GitHub Advisory Database","url":"https://github.com/eclipse-threadx/guix/security/advisories/GHSA-pppm-h3g4-986x","fetched_at":"2026-10-23T20:39:26.410340Z","source_modified_at":"2026-10-02T18:44:56Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-92454","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","GitHub Advisory Database","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/eclipse-threadx/guix/security/advisories/GHSA-pppm-h3g4-986x"}],"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":"2026-10-20T15:21:00.502903Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-20T15:21:42.800Z","content_hash":"067764337bd318cd592d98b6709373db7d7c35a1279108b59ebe4d13eb7915ab"}}
