CVE-2026-13814: Google Chrome Use After Free Vulnerability

CVE-2026-13814 Overview

CVE-2026-13814 is a use-after-free vulnerability [CWE-416] in the Views component of Google Chrome versions prior to 150.0.7871.47. A remote attacker can trigger heap corruption by convincing a user to interact with a crafted HTML page through specific UI gestures. Successful exploitation may lead to arbitrary code execution within the browser process context. Google Chromium classifies the internal severity as High, and the CVSS 3.1 base score is 7.5.

Critical Impact
A remote attacker who lures a user to a malicious HTML page and induces specific UI interactions can corrupt heap memory in Chrome's Views subsystem, potentially enabling code execution in the browser process.

Affected Products

Google Chrome desktop versions prior to 150.0.7871.47
Chromium-based browsers using the vulnerable Views component
All platforms served by the Chrome Stable channel (Windows, macOS, Linux)

Technical Details for CVE-2026-13814

Vulnerability Analysis

The flaw resides in Chrome's Views framework, the cross-platform UI toolkit that renders browser windows, dialogs, menus, and other interactive controls. A use-after-free condition [CWE-416] occurs when the code retains a pointer to a Views object after the underlying memory has been released. Subsequent access to the dangling pointer produces undefined behavior and heap corruption.

An attacker delivers a crafted HTML page that manipulates Views state through DOM operations and script-driven UI activity. The exploit path requires user interaction, such as clicking, dragging, or focus changes that trigger the vulnerable object lifecycle. Chromium's High severity rating reflects the potential for heap layout control and follow-on code execution within the browser process.

Root Cause

The root cause is object lifetime mismanagement in the Views component. Code paths free a UI object while other references remain live, and later dereferences read or write freed memory. Attackers can reclaim the freed allocation with attacker-controlled data, converting the dangling pointer into a primitive for arbitrary read, write, or control-flow hijacking.

Attack Vector

Exploitation requires network delivery of a malicious HTML page and specific UI gestures from the victim. The high attack complexity reflects the need to win a memory reclaim race and to coax the user through the required interaction sequence. No authentication is required, and the scope is unchanged. Successful exploitation impacts confidentiality, integrity, and availability of the browser session.

No public proof-of-concept exploit is currently listed for CVE-2026-13814. Technical details are tracked in Chromium Issue Tracker #511712766.

Detection Methods for CVE-2026-13814

Indicators of Compromise

Chrome renderer or browser process crashes with heap corruption signatures around Views objects
Unexpected child processes spawned by chrome.exe following visits to untrusted sites
Outbound connections from Chrome to newly registered or low-reputation domains hosting HTML payloads
Browser telemetry showing repeated tab crashes tied to specific URLs or UI interactions

Detection Strategies

Inventory installed Chrome versions across the fleet and flag any build below 150.0.7871.47
Monitor endpoint telemetry for Chrome process crashes correlated with WerFault.exe or crashpad_handler invocations
Alert on browser processes writing executables to disk or launching shells (cmd.exe, powershell.exe, /bin/sh)
Correlate web proxy logs with crash events to identify malicious HTML delivery pages

Monitoring Recommendations

Ingest browser crash reports and EDR process telemetry into a SIEM for centralized correlation
Track Chrome version drift and patch compliance as a continuous metric
Watch for anomalous parent-child process chains originating from Chrome renderer processes
Baseline user browsing behavior to surface interactions with unfamiliar domains preceding crashes

How to Mitigate CVE-2026-13814

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
Push the update through enterprise management tools such as Chrome Browser Cloud Management or Group Policy
Verify Chromium-based derivatives (Edge, Brave, Opera, Vivaldi) receive corresponding upstream fixes

Patch Information

Google released the fix in the Chrome Stable channel update documented in the Google Chrome Desktop Update. Administrators should confirm the deployed build is at or above 150.0.7871.47.

Workarounds

Restrict browsing to trusted sites via enterprise URL allowlists until patching completes
Enable Chrome's Site Isolation and Enhanced Safe Browsing to reduce exploit reliability
Educate users to avoid unsolicited links and unexpected UI prompts on untrusted pages
Deploy web content filtering to block known malicious HTML delivery infrastructure
