CVE-2026-14388: Google Chrome ANGLE Information Disclosure

CVE-2026-14388 Overview

CVE-2026-14388 is an out-of-bounds read vulnerability in ANGLE, the graphics translation layer used by Google Chrome. The flaw affects Chrome versions prior to 150.0.7871.46. A remote attacker can trigger the condition by convincing a user to visit a crafted HTML page. Successful exploitation allows the attacker to read data outside allocated buffer boundaries in the renderer process. This can expose sensitive information residing in process memory. The Chromium project rated the security severity as Medium and classified the weakness under CWE-125.

Critical Impact
Remote attackers can leak sensitive data from the Chrome renderer process memory through a crafted web page, requiring only a single user interaction.

Affected Products

Google Chrome Desktop versions prior to 150.0.7871.46
ANGLE graphics component shipped with vulnerable Chrome builds
Chromium-based browsers integrating the affected ANGLE revision

Technical Details for CVE-2026-14388

Vulnerability Analysis

ANGLE (Almost Native Graphics Layer Engine) translates OpenGL ES API calls into the native graphics API of the host platform, such as Direct3D, Metal, or Vulkan. Chrome uses ANGLE to render WebGL and other GPU-accelerated content sandboxed inside the renderer process. The vulnerability allows a crafted HTML page to trigger an out-of-bounds read within ANGLE. The read accesses memory beyond the intended buffer, returning unintended contents to attacker-controlled code paths. Attackers can use this primitive to disclose data from adjacent memory regions, including pointers useful for defeating address space layout randomization (ASLR).

Root Cause

The root cause is a missing or incorrect bounds check inside ANGLE when processing attacker-influenced input from a WebGL or graphics API call. The condition falls under [CWE-125] Out-of-bounds Read. Chromium issue #500476886 tracks the defect and its fix.

Attack Vector

Exploitation is network-based and requires user interaction. The attacker hosts a crafted HTML page that issues specific WebGL or graphics operations when the victim loads the page. When Chrome parses the malicious content, ANGLE performs the out-of-bounds read and returns memory contents that the page's JavaScript can observe. No authentication is required. The vulnerability affects confidentiality but does not directly enable code execution or integrity impact.

No verified proof-of-concept code has been published. Technical details are described in the Chromium Issue Tracker #500476886 and the Google Chrome Desktop Update advisory.

Detection Methods for CVE-2026-14388

Indicators of Compromise

Chrome processes running versions earlier than 150.0.7871.46 after the patch release date
Renderer processes making unusual GPU or WebGL API calls originating from untrusted domains
Browser telemetry showing repeated visits to pages hosting anomalous WebGL shader or texture operations

Detection Strategies

Inventory browser versions across the fleet and flag any Chrome installation below 150.0.7871.46
Monitor web proxy logs for user visits to unclassified domains delivering large WebGL payloads
Correlate renderer crash reports or GPU process anomalies with recent navigation events

Monitoring Recommendations

Enable Chrome enterprise reporting to centralize version and extension inventory data
Ingest browser and endpoint telemetry into a SIEM to correlate suspicious page loads with process memory events
Track outbound network connections from renderer processes to detect exfiltration following information leaks

How to Mitigate CVE-2026-14388

Immediate Actions Required

Update Google Chrome to version 150.0.7871.46 or later on all managed endpoints
Restart Chrome after updating to ensure the patched ANGLE library is loaded
Verify Chromium-based browsers in the environment have absorbed the upstream fix

Patch Information

Google addressed the vulnerability in the Chrome Stable channel update to 150.0.7871.46. Details are published in the Google Chrome Desktop Update release notes. Administrators managing enterprise deployments should push the update through Chrome Browser Cloud Management or their existing software distribution tooling.

Workarounds

Disable WebGL through the --disable-webgl command-line flag or enterprise policy where the feature is not required
Restrict browsing to trusted sites using URL allowlists until the patch is deployed
Isolate high-risk user groups behind remote browser isolation to contain renderer process memory exposure
