{"url":"http://public2.vulnerablecode.io/api/vulnerabilities/90813?format=json","vulnerability_id":"VCID-p4sd-c8xy-7fh4","summary":"WebAssembly Micro Runtime (WAMR) is a lightweight standalone WebAssembly (Wasm) runtime. Prior to version 2.4.4, an out-of-bounds array access issue exists in WAMR's fast interpreter mode during WASM bytecode loading. When frame_ref_bottom and frame_offset_bottom arrays are at capacity and a GET_GLOBAL(I32) opcode is encountered, frame_ref_bottom is expanded but frame_offset_bottom may not be. If this is immediately followed by an if opcode that triggers preserve_local_for_block, the function traverses arrays using stack_cell_num as the upper bound, causing out-of-bounds access to frame_offset_bottom since it wasn't expanded to match the increased stack_cell_num. This issue has been patched in version 2.4.4.","aliases":[{"alias":"CVE-2025-64713"}],"fixed_packages":[],"affected_packages":[],"references":[{"reference_url":"https://github.com/bytecodealliance/wasm-micro-runtime/security/advisories/GHSA-gvx3-gg3x-rjcx","reference_id":"GHSA-gvx3-gg3x-rjcx","reference_type":"","scores":[{"value":"5.1","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:P/A:N/T:P/P:M/B:A/M:M/D:T/2025-11-26T14:50:25Z/"}],"url":"https://github.com/bytecodealliance/wasm-micro-runtime/security/advisories/GHSA-gvx3-gg3x-rjcx"},{"reference_url":"https://github.com/bytecodealliance/wasm-micro-runtime/releases/tag/WAMR-2.4.4","reference_id":"WAMR-2.4.4","reference_type":"","scores":[{"value":"5.1","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:P/A:N/T:P/P:M/B:A/M:M/D:T/2025-11-26T14:50:25Z/"}],"url":"https://github.com/bytecodealliance/wasm-micro-runtime/releases/tag/WAMR-2.4.4"}],"weaknesses":[{"cwe_id":119,"name":"Improper Restriction of Operations within the Bounds of a Memory Buffer","description":"The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer."}],"exploits":[],"severity_range_score":"5.1 - 5.1","exploitability":null,"weighted_severity":null,"risk_score":null,"resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-p4sd-c8xy-7fh4"}
