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":"2025-10-24T21:54:52.578+00:00","modifiedAt":"2025-10-27T15:22:22.914+00:00","affected":[{"ecosystem":"Vendor product","name":"wasmtime","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"bytecodealliance\",\n                    \"product\": \"wasmtime\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 38.0.0, < 38.0.3\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","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","score":2.1,"severity":"LOW"}],"references":["https://github.com/bytecodealliance/wasmtime/security/advisories/GHSA-4h67-722j-5pmc","https://github.com/bytecodealliance/wasmtime/pull/11592","https://github.com/bytecodealliance/wasmtime/commit/192f2fcdadfec9d0cf6b58548a85a7307450cbf5"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2025-62711","license":"CVE Program Terms of Use","key":"cve-program:CVE-2025-62711","identifiers":["CVE-2025-62711"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
