The decode_move() function initializes a read pointer into a decompressed buffer, but a subsequent reallocation of that same buffer during move-table processing leaves the pointer dangling. An attacker could exploit this by providing a specially crafted AVI file containing a malicious RASC video stream. When a user opens or plays the file, the decoder reads from freed heap memory, which could lead to a denial of service (crash).","published_at":"2026-06-19T10:55:03.634000Z","last_modified_at":null,"cvss_v3_score":6.5,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","cvss_v3_severity":"MEDIUM","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-416"],"nvd_references":["https://access.redhat.com/security/cve/CVE-2026-12706","https://bugzilla.redhat.com/show_bug.cgi?id=2490710","https://lists.ffmpeg.org/archives/list/ffmpeg-devel@ffmpeg.org/message/TTRIJZA7UL6KJTEDMMBGZPLLJERJ3EFX/","https://patchwork.ffmpeg.org/project/ffmpeg/patch/177766314111.63.10674887811034989327@29965ddac10e/"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:28:57.643719Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"R","value_label":"Required"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"N","value_label":"None"},{"metric":"I","name":"Integrity","value":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[],"exploit_refs":[],"news":[],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-12706","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2490710","source_type":"MISC","tags":[]},{"url":"https://lists.ffmpeg.org/archives/list/ffmpeg-devel@ffmpeg.org/message/TTRIJZA7UL6KJTEDMMBGZPLLJERJ3EFX/","source_type":"MAILING_LIST","tags":["mailing-list"]},{"url":"https://patchwork.ffmpeg.org/project/ffmpeg/patch/177766314111.63.10674887811034989327@29965ddac10e/","source_type":"MISC","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-06-19T10:55:03.634000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:50:44.924477Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:50:44.924477Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:50:44.924477Z","label":"CVSS score revised","source":"cvelistv5"}]}
