CVE-2026-54912

WebAssembly Micro Runtime WAMR is a lightweight standalone WebAssembly Wasm runtime. Prior to 2.4.5, the two-pass fast interpreter loader in core/iwasm/interpreter/wasmloader.c can make inconsistent constant-table decisions between the sizing pass and the emitting pass. After duplicate constants...

CVE-2026-54912

The WebAssembly Micro Runtime (WAMR) (prior to version 2.4.5 ) contains a heap buffer overflow vulnerability in the two-pass fast interpreter loader located at core/iwasm/interpreter/wasm_loader.c. The root cause is an inconsistent constant-table decision between the sizing and emitting passes; s...
