CVE-2026-14151: Google Chrome RCE Vulnerability

CVE-2026-14151 Overview

CVE-2026-14151 affects Google Chrome versions prior to 150.0.7871.47. The vulnerability resides in the AI component and stems from an inappropriate implementation that permits sandbox escape. A remote attacker who has already compromised the renderer process can escape the Chrome sandbox through a crafted HTML page. Google classifies the Chromium security severity as Low, while the NVD assigns a CVSS 3.1 score of 8.3 due to the scope change and high impact on confidentiality, integrity, and availability. The weakness maps to [CWE-669] Incorrect Resource Transfer Between Spheres and [CWE-693] Protection Mechanism Failure.

Critical Impact
A successful sandbox escape allows attacker-controlled code in a compromised renderer to break out of the browser sandbox, enabling execution in a higher-privilege context on the host system.

Affected Products

Google Chrome versions prior to 150.0.7871.47
Chromium-based browsers sharing the vulnerable AI component code
Desktop platforms serviced by the Chrome Stable channel update

Technical Details for CVE-2026-14151

Vulnerability Analysis

The vulnerability exists in Chrome's AI subsystem and is categorized as an inappropriate implementation flaw. Chrome enforces a multi-process architecture where untrusted web content executes inside a sandboxed renderer process with limited privileges. The AI feature crosses this trust boundary to service requests originating from web content. The flawed implementation allows an attacker who already controls the renderer to leverage this cross-boundary interaction to escape the sandbox. The chained nature of the attack requires prior renderer compromise, which explains the High attack complexity in the CVSS vector.

Root Cause

The root cause is protection mechanism failure between the renderer sandbox and higher-privileged Chrome components handling AI functionality [CWE-693]. Data or control flow transfers between these spheres without sufficient validation [CWE-669]. The AI component exposes an interface that trusts renderer-supplied input beyond its intended threat model. This trust misalignment lets a compromised renderer influence privileged code paths.

Attack Vector

Exploitation is network-based and requires user interaction. The attacker first lures the victim to a crafted HTML page. The page delivers a renderer exploit that compromises the sandboxed process. The attacker then invokes the vulnerable AI interface from within the renderer to trigger the sandbox escape. Because the escape crosses process trust boundaries, the CVSS scope is Changed, and impact on confidentiality, integrity, and availability is High. The EPSS score is 0.22% with a percentile of 12.5, and no public exploit is currently listed.

No verified proof-of-concept code is available. Refer to the Chromium Issue Tracker Entry and the Google Chrome Update Announcement for technical details as they become public.

Detection Methods for CVE-2026-14151

Indicators of Compromise

Chrome browser processes spawning unexpected child processes outside the standard renderer, GPU, and utility hierarchy
Anomalous inter-process communication (IPC) traffic between renderer processes and the AI service component
Chrome version strings reporting builds earlier than 150.0.7871.47 in endpoint inventory

Detection Strategies

Inventory installed Chrome versions across the fleet and flag any host running a build below 150.0.7871.47
Monitor for renderer processes attempting to access resources outside the sandbox policy, including file system paths and privileged handles
Correlate visits to newly registered or low-reputation domains with subsequent unusual Chrome child process creation

Monitoring Recommendations

Enable browser process telemetry ingestion into a centralized SIEM for behavioral baselining
Alert on Chrome processes writing executables or scheduled tasks, which are atypical for sandboxed browser workloads
Track Chrome update compliance through endpoint management tooling and generate alerts for stale versions

How to Mitigate CVE-2026-14151

Immediate Actions Required

Update Google Chrome to version 150.0.7871.47 or later on all managed endpoints
Restart Chrome after the update to ensure the patched binaries are loaded into memory
Verify auto-update mechanisms are functional and not blocked by policy or network filtering

Patch Information

Google addressed CVE-2026-14151 in the Chrome Stable channel release 150.0.7871.47. Details are documented in the Google Chrome Update Announcement. Administrators managing Chromium-based browsers should confirm that the upstream fix has been integrated into their downstream build.

Workarounds

Disable or restrict Chrome AI features through enterprise policy where operationally feasible until patching is complete
Enforce site isolation and strict content security policies to reduce the likelihood of an initial renderer compromise
Apply network-level filtering to block access to untrusted or newly observed domains that could host the crafted HTML page

bash

# Verify Chrome version on Linux endpoints
google-chrome --version

# Windows registry check for installed Chrome version
reg query "HKLM\SOFTWARE\Google\Chrome\BLBeacon" /v version

# Enterprise policy to force update channel (Windows)
reg add "HKLM\SOFTWARE\Policies\Google\Update" /v UpdateDefault /t REG_DWORD /d 1 /f
