In versions from 38.0.0 to before 38.0.3, the implementation of component-model related host-to-wasm trampolines in Wasmtime contained a bug where it's possible to carefully craft a component, which when called in a specific way, would crash the host with a segfault or assert failure. Wasmtime 38.0.3 has been released and is patched to fix this issue. There are no workarounds.","state":0,"publishedAt":"2025-10-24T22:15:49.85+00:00","modifiedAt":"2026-10-08T11:10:00.25+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:P/VC:N/VI:N/VA:L/SC:N/SI:N/SA:L/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":2.1,"severity":"LOW"},{"system":"CVSS 3.1 · nvd@nist.gov · Primary","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:L","score":3.1,"severity":"LOW"}],"references":["https://github.com/bytecodealliance/wasmtime/commit/192f2fcdadfec9d0cf6b58548a85a7307450cbf5","https://github.com/bytecodealliance/wasmtime/pull/11592","https://github.com/bytecodealliance/wasmtime/security/advisories/GHSA-4h67-722j-5pmc"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2025-62711","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-755"],"productCriteria":["cpe:2.3:a:bytecodealliance:wasmtime:*:*:*:*:*:rust:*:*"],"sourceDates":{"published":"2025-10-24T22:15:49.850","lastModified":"2026-10-08T11:10:00.250"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
