vm2 before 3.11.7 exposes Node's shared Buffer pool to sandboxed code, allowing disclosure of host memory used by Buffer.from, Buffer.concat, and related allocations. Sandboxed code can read and write to host-realm buffers by acquiring ArrayBuffers from small allocations, leading to sensitive data exposure and potential denial-of-service.
