The vulnerability is caused by insufficient validation of external-variable pointers, which may lead to invalid free in yr_rules_destroy() or wild pointer access in yr_object_create(). An attacker can provide a specially crafted .yrc file that causes memory corruption and application crash.","state":0,"publishedAt":"2026-09-22T00:00:00+00:00","modifiedAt":"2026-09-25T19:47:47.785+00:00","affected":[{"ecosystem":"Vendor product","name":"n/a","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"n/a\",\n                    \"product\": \"n/a\",\n                    \"versions\": [\n                        {\n                            \"version\": \"n/a\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://github.com/VirusTotal/yara/issues/2239","https://github.com/VirusTotal/yara/pull/2244","https://github.com/VirusTotal/yara/pull/2244/changes/8d7bef643ee5fa2381e235bcedf80170a6b00d3b"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-88340","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-88340","identifiers":["CVE-2026-88340"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
