In versions 0.41.0, 0.41.1, 0.42.0 through 0.47.1, 0.50.0 through 0.51.2 and 1.0.0, Wasmi's linear memory implementation leads to a Use After Free vulnerability, triggered by a WebAssembly module under certain memory growth conditions. This issue potentially leads to memory corruption, information disclosure, or code execution. This issue is fixed in versions 0.41.2, 0.47.1, 0.51.3 and 1.0.1. To workaround this issue, consider limiting the maximum linear memory sizes where feasible.","state":0,"publishedAt":"2025-12-09T16:18:21.91+00:00","modifiedAt":"2026-10-14T21:10:00.183+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.4,"severity":"HIGH"},{"system":"CVSS 3.1 · nvd@nist.gov · Primary","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8,"severity":"HIGH"}],"references":["https://github.com/wasmi-labs/wasmi/security/advisories/GHSA-g4v2-cjqp-rfmq"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2025-66627","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-416"],"productCriteria":["cpe:2.3:a:wasmi-labs:wasmi:*:*:*:*:*:rust:*:*","cpe:2.3:a:wasmi-labs:wasmi:1.0.0:*:*:*:*:rust:*:*"],"sourceDates":{"published":"2025-12-09T16:18:21.910","lastModified":"2026-10-14T21:10:00.183"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
