Prior to version 2.4.4, an out-of-bounds array access issue exists in WAMR&#8217;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&#8217;t expanded to match the increased stack_cell_num. This issue has been patched in version 2.4.4.<\/p>\n<p>Severity: 0.0 | NA<\/p>\n<p>Visit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID : CVE-2025-64713 Published : Nov. 25, 2025, 10:13 p.m. | 1\u00a0hour, 9\u00a0minutes ago Description : WebAssembly Micro Runtime (WAMR) is a lightweight standalone WebAssembly (Wasm) runtime.
