CVE-2024-35410Public exploit

Interpreter crash via out-of-bounds heap write

Published Nov 8, 2024 · Updated Nov 18, 2024

Heap buffer overflow in Kanaka WAC commit 385e1 allows local users to crash the interpreter with a crafted WebAssembly file. In interpret at wa.c:993, module loading performs a one-byte write immediately before a one-byte heap allocation, as demonstrated by AddressSanitizer. Exploitation requires local execution of the crafted file through wace and interrupts only that interpreter process; no confidentiality or integrity impact is reported.
