AlmaLinux 9.2 [TuxCare] Security Update: nodejs / nodejs-devel / nodejs-docs / nodejs-full-i18n / etc Multiple Vulnerabilities (ALMALINUX9.2:CLSA-2026:1769775296)

The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1769775296 advisory. - A flaw in Node.js's buffer allocation logic can expose uninitialized memory when allocations are interrupted, when using the vm...

CVE-2026-68265

A flaw was found in the Linux kernel. Specifically, within the drm/xe/vm module, an out-of-bounds access can occur when handling the DRMXECONSULTMEMADVISEPREFLOC region for a Buffer Object BO Virtual Memory Area VMA. This happens because a value of -1 is incorrectly used as an index into a memory...

Astra Linux – Vulnerability in Node.js

A flaw in Node.js’s buffer allocation logic can expose uninitialized memory when allocations are interrupted, especially when using the vm module with the timeout option. Under certain timing conditions, buffers allocated using Buffer.alloc and other TypedArray instances like Uint8Array may conta...

browserstack-runner vulnerable to Remote Code Execution via vm sandbox escape in _log HTTP handler

Summary The HTTP handler /log in lib/server.js lines 491–515 of browserstack-runner passes unauthenticated user-supplied data to vm.runInNewContext combined with eval, enabling a sandbox escape and arbitrary code execution on the host system. Details When browserstack-runner starts, it creates an...

CVE-2026-45102

CVE-2026-45102 concerns OneUptime, an open-source monitoring platform. Prior to version 10.0.98, OneUptime used Node.js vm module as an isolation primitive, which is not intended for security boundaries and can be escaped via error objects and infinite recursion, potentially enabling remote code ...

CVE-2026-45102: Protection Mechanism Failure

OneUptime is an open-source monitoring and observability platform. Prior to 10.0.98, OneUptime uses the Node.js' vm module as an isolation primitive. This API was not designed for that and can be escaped via error objects and infinite recursion. This vulnerability is fixed in 10.0.98...

Arbitrary Code Injection

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 Arbitrary Code Injection through lib/builtin.js. An attacker can execute host code when the allowlist includes -X or uses and then calls...

nodejs: Nodejs uninitialized memory exposure

A memory exposure flaw has been discovered in Node.js. A flaw in Node.js's buffer allocation logic can expose uninitialized memory when allocations are interrupted, when using the vm module with the timeout option. Under specific timing conditions, buffers allocated with Buffer.alloc and other...

Information Disclosure

Node.js is vulnerable to Information Disclosure. The vulnerability is due to improper buffer allocation handling when using the vm module with the timeout option, where interrupted allocations may return buffers containing uninitialized memory, potentially exposing leftover data such as tokens or...

CVE-2026-30887: Improper Control of Generation of Code

OneUptime is a solution for monitoring and managing online services. Prior to 10.0.18, OneUptime allows project members to run custom Playwright/JavaScript code via Synthetic Monitors to test websites. However, the system executes this untrusted user code inside the insecure Node.js vm module. By...

OneUptime:: node:vm sandbox escape in probe allows any project member to achieve RCE

Summary OneUptime lets project members write custom JavaScript that runs inside monitors. The problem is it executes that code using Node.js's built-in vm module, which Node.js itself documents as "not a security mechanism — do not use it to run untrusted code." The classic one-liner escape gives...

CVE-2026-27574

OneUptime is a solution for monitoring and managing online services. In versions 9.5.13 and below, custom JavaScript monitor feature uses Node.js's node:vm module explicitly documented as not a security mechanism to execute user-supplied code, allowing trivial sandbox escape via a well-known...
