Prior to 9.2.0670, get_text_props() in src/textprop.c reads a uint16 property count stored inline after a line's text and returns it as the number of 32-byte textprop_T entries that follow. The only check is a floor that guarantees room for a single entry; the count is never checked against the amount of data actually present. A line that declares a large count while carrying little data causes consumers to read far past the end of the line buffer. Such a line can be delivered through a crafted undo file, leading to a crash. This vulnerability is fixed in 9.2.0670.","published_at":"2026-06-25T15:28:50.474000Z","last_modified_at":null,"cvss_v3_score":5.3,"cvss_v3_vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:L/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-125"],"nvd_references":["https://github.com/vim/vim/security/advisories/GHSA-f36c-2qcp-7gpw","https://github.com/vim/vim/commit/b2338ca90643e2f01ecb6547c1172716aaec4f79","https://github.com/vim/vim/releases/tag/v9.2.0670"],"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":"2026-06-28T17:55:42.709123Z","updated_at":"2026-06-28T23:30:58.474828Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"L","value_label":"Local"},{"metric":"AC","name":"Attack Complexity","value":"H","value_label":"High"},{"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":"L","value_label":"Low"},{"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":[{"vendor_slug":"vim","vendor_name":"vim","product_slug":"vim","product_name":"vim","version_start":"< 9.2.0670","version_start_inclusive":true,"version_end":"< 9.2.0670","version_end_inclusive":true,"cpe23_uri":"cve5:vim:vim:< 9.2.0670:< 9.2.0670"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/vim/vim/security/advisories/GHSA-f36c-2qcp-7gpw","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/vim/vim/commit/b2338ca90643e2f01ecb6547c1172716aaec4f79","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/vim/vim/releases/tag/v9.2.0670","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-06-25T15:28:50.474000Z","label":"CVE published","source":null}]}
