CVE-2024-35421Public exploit

Interpreter crash via null-pointer dereference

Published Nov 8, 2024 · Updated Nov 12, 2024

Null-pointer dereference in VMIR e8117 allows local users to crash the interpreter by processing a crafted WebAssembly file. The wasm_parse_block function in src/vmir_wasm_parser.c reads through a null pointer while parsing the malformed module's code section, causing a segmentation fault. Execution of the attacker-supplied file requires user interaction, and the demonstrated consequence is limited to aborting the VMIR process.
