Researchers have developed Walma, a novel framework designed to detect memory corruption within WebAssembly (Wasm) environments. Walma transforms snapshots of Wasm linear memory into images, which are then analyzed by a convolutional neural network to identify tampering. This approach can detect modifications that traditional byte and texture analyses miss, even those not triggered by program input. The system has demonstrated effectiveness on real-world CVE-affected applications, requiring significant memory overwrites to evade detection, and offers practical attestation costs for continuous memory integrity checks.
