CVE-2026-92947

A flaw was found in vm2. The sandbox environment inadvertently exposes the host system's shared memory buffer pool to sandboxed code. An attacker running untrusted code inside the sandbox can access and modify these shared buffers, resulting in unauthorized information disclosure of host memory o...

CVE-2026-100723 vm2 before 3.12.2 Memory Disclosure via zlib Buffer Pool

vm2 before 3.12.2 does not apply its Buffer backing-store ownership invariant byteOffset === 0 and buffer.byteLength === length to Buffers returned from host builtin modules. When an application explicitly exposes Node's zlib module through NodeVM's builtin allowlist require: builtin: 'zlib' ,...

CVE-2026-100723

The vm2 library before version 3.12.2 is vulnerable to a memory disclosure and corruption issue due to a failure in applying Buffer backing-store ownership invariants for host builtin modules. When an application exposes the zlib module via NodeVM's builtin allowlist, zlib.deflateSync can return ...

Information Exposure

Overview vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules. Affected versions of this package are vulnerable to Information Exposure via the Buffer pool. An attacker can access and manipulate host memory by leveraging sandboxed code to acquire ArrayBuffers from...

CVE-2026-92947

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 dat...

CVE-2026-92947

CVE-2026-92947 affects the vm2 Node.js sandboxing library prior to version 3.11.7 . The vulnerability arises because Node's shared Buffer pool is exposed to sandboxed code: sandboxed scripts can acquire ArrayBuffers from small allocations (e.g., Buffer.from, Buffer.concat), gaining read and write...

CVE-2026-92947: Exposure of Sensitive Information to an Unauthorized Actor

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 dat...

Astra Linux – Vulnerability in Wayland

An internal reference count is maintained on the buffer pool; this count increments every time a new buffer is created from the pool. The reference count is stored as an integer. On LP64 systems, this can lead to an overflow if the client creates a large number of wlshm buffer objects, or if it...

CVE-2026-14696 Ethernet bridge RX packet leak enables denial of service via RX buffer-pool exhaustion

When Ethernet bridging is enabled CONFIGNETETHERNETBRIDGE, ethbridgeinputprocess in subsys/net/l2/ethernet/bridge/bridgeinput.c decides how each frame received on a bridge member interface is handled. For frames that must also be delivered to the local stack, the code called ethbridgehandlelocall...

CVE-2026-14696

Zephyr RTOS Ethernet bridging contains an RX packet leak in eth_bridge_input_process() (subsys/net/l2/ethernet/bridge/bridge_input.c). When Ethernet bridging is enabled (CONFIG_NET_ETHERNET_BRIDGE), frames delivered to the local stack via eth_bridge_handle_locally() return NET_OK without actually...
