CVE-2026-14413: Google Chrome ANGLE Sandbox Escape Flaw

CVE-2026-14413 Overview

CVE-2026-14413 is an uninitialized memory use vulnerability in ANGLE, the graphics abstraction layer used by Google Chrome to translate OpenGL ES calls to native graphics APIs. The flaw affects Chrome versions prior to 150.0.7871.46. A remote attacker who has already compromised the renderer process can use a crafted HTML page to leverage this issue and potentially escape the Chrome sandbox. The Chromium project classified the security severity as High. The vulnerability is tracked under CWE-457: Use of Uninitialized Variable.

Critical Impact
Successful exploitation chained with a renderer compromise enables sandbox escape, giving an attacker code execution outside the renderer boundary.

Affected Products

Google Chrome versions prior to 150.0.7871.46
Chromium-based browsers that ship the vulnerable ANGLE component
Desktop platforms receiving updates through the Chrome Stable channel

Technical Details for CVE-2026-14413

Vulnerability Analysis

The vulnerability resides in ANGLE (Almost Native Graphics Layer Engine), which Chrome uses to implement WebGL and other GPU-facing features. ANGLE runs in a more privileged context than the renderer, making it a common target for sandbox escape research. An uninitialized variable is read before being assigned a defined value. When attacker-controlled state influences that memory region, the resulting behavior can be steered toward attacker goals such as controlled memory disclosure or corruption in the GPU process.

Exploitation requires that the attacker first compromise the renderer process, then send crafted graphics API calls to the GPU process through the Chrome IPC boundary. User interaction is required, and attack complexity is high, since the attacker must chain this issue with a prior renderer exploit and reliably shape the uninitialized memory contents.

Root Cause

The root cause is classified as CWE-457: Use of Uninitialized Variable. A code path in ANGLE consumes a value or object field that has not been initialized on all reachable branches. Depending on prior allocations, the memory can contain stale attacker-controlled data. This condition undermines assumptions that downstream graphics code makes about validated input.

Attack Vector

The attack chain begins with the victim visiting a crafted HTML page that first exploits an independent renderer vulnerability. Once code runs inside the renderer, the attacker sends malformed graphics commands through the ANGLE interface to reach the uninitialized read. Successful manipulation of the uninitialized state can be used to influence control flow or memory contents in the GPU process, achieving a sandbox escape. See the Chromium Issue Tracker Entry and the Google Chrome Stable Update for public references.

Detection Methods for CVE-2026-14413

Indicators of Compromise

Chrome browser processes running versions earlier than 150.0.7871.46 on managed endpoints.
Unexpected crashes or restarts of the Chrome GPU process (--type=gpu-process) correlated with browsing activity.
Child processes spawned by the Chrome GPU process that are not part of normal browser operation.
Outbound network connections from GPU or renderer helper processes to previously unseen domains.

Detection Strategies

Inventory installed Chrome versions across the fleet and flag any build older than 150.0.7871.46.
Monitor for renderer or GPU process crashes accompanied by shellcode-like behavior such as unexpected file writes or process creation.
Correlate visits to untrusted HTML content with subsequent anomalies in Chrome child processes.
Hunt for post-exploitation activity such as credential access, persistence writes, or LOLBin execution originating from Chrome process trees.

Monitoring Recommendations

Enable process ancestry logging on endpoints so Chrome sandbox escapes are visible in EDR telemetry.
Alert on Chrome GPU or utility processes creating new executables, scripts, or scheduled tasks.
Track browser version telemetry through management tooling and enforce update compliance SLAs.
Retain browser crash reports centrally for at least 30 days to support retrospective investigation.

How to Mitigate CVE-2026-14413

Immediate Actions Required

Update Google Chrome to version 150.0.7871.46 or later on all Windows, macOS, and Linux endpoints.
Update any Chromium-based browsers and embedded frameworks once vendors ship builds that incorporate the ANGLE fix.
Restart Chrome after updating to ensure the patched binaries are loaded into all renderer and GPU processes.
Verify update deployment through endpoint management reporting rather than relying on user-initiated updates.

Patch Information

Google addressed this vulnerability in the Chrome Stable channel release documented in the Google Chrome Stable Update. The fix is included in Chrome 150.0.7871.46 and later. Technical tracking is available in the Chromium Issue Tracker Entry, which is subject to Chromium's standard restricted-access policy for security bugs.

Workarounds

Disable hardware acceleration in Chrome settings to reduce reliance on ANGLE code paths until the patch is deployed.
Restrict browsing to trusted sites through enterprise policy while updates propagate.
Deploy Chrome enterprise policies that enforce automatic updates and prevent users from downgrading.

bash

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

# Windows: query installed Chrome version from the registry
reg query "HKLM\SOFTWARE\Google\Chrome\BLBeacon" /v version

# Enterprise policy example: force automatic updates (Windows registry)
reg add "HKLM\SOFTWARE\Policies\Google\Update" /v UpdateDefault /t REG_DWORD /d 1 /f
