{"id":"CVE-2026-110654","summary":"libzvbi through 0.2.45 Out-of-Bounds Write via Teletext DRCS convert_drcs","details":"libzvbi through 0.2.45 contains an out-of-bounds write vulnerability in the Teletext decoder that allows attackers to corrupt memory by supplying unvalidated DRCS pixel-mode values in X/28/3 packets. 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.","modified":"2026-10-15T02:47:31.331376825Z","published":"2026-10-14T15:01:21.898Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-787"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110654.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110654.json"},{"type":"PACKAGE","url":"https://github.com/zapping-vbi/zvbi"},{"type":"ARTICLE","url":"https://github.com/zapping-vbi/zvbi/blob/d3a5ee9f2b047bf16cd1ee5ccf6ec05ee75409d0/src/packet.c#L447"},{"type":"EVIDENCE","url":"https://hackmd.io/@haind-pwn/zvbi-teletext-drcs-mode-oob-write"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-110654"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/libzvbi-through-0.2.45-out-of-bounds-write-via-teletext-drcs-convert-drcs"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/zapping-vbi/zvbi","events":[{"introduced":"0"},{"last_affected":"d3a5ee9f2b047bf16cd1ee5ccf6ec05ee75409d0"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"last_affected":"0.2.45"}]}}],"versions":["v0.2.45","v0.2.44","v0.2.43","v0.2.42","v0.2.41","v0.2.40","v0.2.39","v0.2.38","v0.2.37","v0.2.36"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-110654.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N"}]}
