CVE-2024-35422Public exploit

Process crash via out-of-bounds read in wasm_call

Published Nov 8, 2024 · Updated Mar 14, 2025

Heap buffer overflow in the wasm_call parser in Andreas Smas VMIR e8117 allows local users to crash its process via a crafted WebAssembly file. The function performs an eight-byte read from eight bytes before an 11-byte heap allocation created for a named basic block while loading the module. Execution of attacker-supplied WebAssembly and user interaction are required; the public report demonstrates a process crash, not code execution.
