CVE-2026-44004

A flaw was found in vm2 before 3.11.0. Sandboxed code can call Buffer.alloc with arbitrary size to allocate on the host heap synchronously; vm2 timeout cannot interrupt the native C++ call, allowing a single request to exhaust host memory and crash the process. Fixed in 3.11.0...

CVE-2024-36332

CVE-2024-36332 concerns improper isolation of GPU hardware register space. The AMD bulletin/related records describe a vulnerability where a compromised Guest VM with privileged access could access a restricted range of GPU MMIO registers, potentially forcing a host OS reboot and causing Denial o...

CVE-2026-44004

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.0, sandboxed code can call Buffer.alloc with an arbitrary size to allocate memory directly on the host heap. Because Buffer.alloc is a synchronous C++ native call, vm2's timeout option cannot interrupt it. A single request can exhaust ho...
