Attackers can send a crafted Teletext stream decoded via vbi_decode with every slot set to DRCS_MODE_6_5_4, causing convert_drcs to overflow chars[48][60] and crash the application.","categories":["Unclassified"],"product":"libzvbi","vendor":"zapping-vbi","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-110654","source_modified_at":"2026-10-20T01:26:18.324Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"libzvbi","vendor":"zapping-vbi","versions":[{"version":"0","status":"affected","versionType":"semver","lessThanOrEqual":"0.2.45"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6.9,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00172,"percentile":0.06273,"score_date":"2026-10-23"},"published_at":"2026-10-14T15:01:21.898Z","modified_at":"2026-10-20T01:26:18.324Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-110654","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-20T01:26:18.324Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-110654","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://hackmd.io/@haind-pwn/zvbi-teletext-drcs-mode-oob-write","tags":["technical-description","exploit"]},{"source":"CVE List","url":"https://github.com/zapping-vbi/zvbi/blob/d3a5ee9f2b047bf16cd1ee5ccf6ec05ee75409d0/src/packet.c#L447","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/zapping-vbi/zvbi","tags":["product"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/libzvbi-through-0.2.45-out-of-bounds-write-via-teletext-drcs-convert-drcs","tags":["third-party-advisory"]}],"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":"2026-10-20T01:25:53.736590Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-20T01:26:18.324Z","content_hash":"67b13a859d642e6ab3f7661ccf18f0389eed7ccb5c0d77e1b5a1b7a8161a634d"}}
