{"id":"CVE-2025-62711","summary":"Wasmtime vulnerable to segfault when using component resources","details":"Wasmtime is a runtime for WebAssembly. 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.","aliases":["GHSA-4h67-722j-5pmc","RUSTSEC-2025-0112"],"modified":"2026-04-10T05:33:13.888106Z","published":"2025-10-24T21:54:52.578Z","database_specific":{"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/62xxx/CVE-2025-62711.json","cwe_ids":["CWE-755"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/62xxx/CVE-2025-62711.json"},{"type":"ADVISORY","url":"https://github.com/bytecodealliance/wasmtime/security/advisories/GHSA-4h67-722j-5pmc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-62711"},{"type":"FIX","url":"https://github.com/bytecodealliance/wasmtime/commit/192f2fcdadfec9d0cf6b58548a85a7307450cbf5"},{"type":"FIX","url":"https://github.com/bytecodealliance/wasmtime/pull/11592"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/bytecodealliance/wasmtime","events":[{"introduced":"0"},{"fixed":"d9dc16b28c36609f9f1e08be3f9e8b799eafd59c"}]}],"versions":["cranelift-v0.60.0","cranelift-v0.61.0","cranelift-v0.69.0","v0.12.0","v0.16.0","v0.17.0","v0.18.0","v0.19.0","v0.20.0","v0.21.0","v0.22.0","v0.23.0","v0.24.0","v0.25.0","v0.26.0","v0.27.0","v0.28.0","v0.29.0","v0.30.0","v0.31.0","v0.32.0","v0.33.0","v0.34.0","v0.35.0","v38.0.1","v38.0.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-62711.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"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"}]}
