CVE-2026-92947— vm2 before 3.11.7 Memory Disclosure via Buffer Pool

Quick assessment

Affected
patriksimek vm2
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

vm2 在 3.11.7 之前的版本会将 Node.js 的共享缓冲区（Buffer）池暴露给沙箱代码，使得通过 、 及相关内存分配使用的宿主内存可以被访问。沙箱代码可以通过获取小分配的 ArrayBuffer 来读取和写入宿主域（host-realm）的缓冲区，从而导致敏感数据泄露以及潜在的服务拒绝（DoS）问题。

Vulnerability Title
vm2 before 3.11.7 Memory Disclosure via Buffer Pool
Source: CVE Program / CVE List V5
Vulnerability Description
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.
