CVE-2026-92961 · vm2 before 3.11.6 Memory Exhaustion DoS via bufferAllocLimit Bypass

This page contains facts from public vulnerability sources. Check the original advisory before updating.

vm2 before 3.11.6 fails to enforce bufferAllocLimit on ArrayBuffer, SharedArrayBuffer, and TypedArray constructors, allowing attackers to allocate arbitrary host memory. Attackers can bypass the buffer allocation cap by using these V8 intrinsics to exhaust host process memory and trigger out-of-memory conditions.
