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-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...

qemu-kvm: 'qemu-img info' leads to host file read/write

A flaw was found in the QEMU disk image utility qemu-img 'info' command. A specially crafted image file containing a json: value describing block devices in QMP could cause the qemu-img process on the host to consume large amounts of memory or CPU time, leading to denial of service or read/write ...
