vm2 has Memory Exhaustion DoS via bufferAllocLimit Bypass 0 The vm2 sandbox module has a vulnerability in its buffer allocation limit defense that can be bypassed using ArrayBuffer, SharedArrayBuffer, or TypedArray constructors. These constructors allocate host memory through the same underlying C++ path as Buffer.alloc but are not subject to the bufferAllocLimit cap. This allows an attacker to exhaust host memory synchronously, causing a denial of service by out-of-memory kills in constrained environments such as Docker, Kubernetes, or AWS Lambda. The vulnerability affects vm2 versions prior to 3.11.6 and all Node.js versions. A patch is available. Join the discussion | GCVE Database | 08/17/2026, 17:32:57 UTC Added: 08/17/2026, 22:36:09 UTC |
