CVE-2026-14006 Overview
CVE-2026-14006 is a use-after-free vulnerability in the Navigation component of Google Chrome. The flaw affects all Chrome versions prior to 150.0.7871.47. A remote attacker can exploit the issue by serving a crafted HTML page to a targeted user. Successful exploitation allows arbitrary code execution within the browser process context. The vulnerability is tracked as CWE-416: Use After Free and requires user interaction, typically visiting a malicious website.
Critical Impact
Remote attackers can execute arbitrary code in the browser process by luring users to a crafted HTML page, enabling sandbox-adjacent compromise and follow-on exploitation.
Affected Products
- Google Chrome versions prior to 150.0.7871.47
- Chromium-based browsers sharing the affected Navigation code path
- Desktop Chrome distributions across Windows, macOS, and Linux stable channels

Technical Details for CVE-2026-14006
Vulnerability Analysis
The vulnerability resides in Chrome's Navigation component, which manages page loads, history entries, and frame lifecycle transitions. A use-after-free condition occurs when the Navigation code retains a pointer to an object that has already been freed during a navigation state transition. When the dangling pointer is dereferenced, attacker-controlled memory can be reused to influence program flow. Chromium classified the security severity as Medium, but the NVD assessment reflects the full remote code execution impact within the renderer process.
Root Cause
The root cause is object lifetime mismanagement inside the Navigation subsystem. During complex navigation sequences, such as cross-document transitions or frame detach events, a heap-allocated object is released while still referenced by a callback or state machine. Subsequent access reads or writes freed memory, corrupting internal state. This class of bug in Blink and Content layers frequently leads to arbitrary code execution when combined with a heap grooming primitive delivered through JavaScript.
Attack Vector
Exploitation requires a user to load an attacker-controlled HTML page. The page uses JavaScript and DOM manipulation to trigger the vulnerable navigation state transition, then reclaims the freed allocation with attacker-controlled data. Once the dangling reference is used, control flow can be redirected to shellcode or ROP chains staged in the renderer heap. The attacker still needs to chain a sandbox escape to achieve full host compromise, but code execution in the renderer already enables cross-origin data theft and credential exposure.
The vulnerability manifests during navigation lifecycle handling in Chromium's Content layer. Refer to the Google Chrome Update Announcement and the Chromium Issue Tracker Entry for upstream details.
Detection Methods for CVE-2026-14006
Indicators of Compromise
- Chrome renderer processes crashing with access violations or heap corruption signatures shortly after visiting an untrusted site
- Unexpected child processes spawned by chrome.exe or Google Chrome Helper (Renderer) following navigation events
- Outbound connections from renderer processes to newly registered or low-reputation domains hosting HTML payloads
Detection Strategies
- Inventory installed Chrome versions across the fleet and flag any host running a build earlier than 150.0.7871.47
- Monitor for browser exploitation patterns such as renderer crashes followed by code execution attempts, sandbox escape indicators, or suspicious command-line launches
- Correlate web proxy logs with endpoint telemetry to identify users who visited domains delivering exploit HTML pages
Monitoring Recommendations
- Enable browser telemetry and crash reporting to central logging for detection engineering review
- Alert on process ancestry anomalies where Chrome renderer processes spawn shells, scripting engines, or LOLBins
- Track version compliance of Chrome and Chromium-derived browsers as an ongoing configuration management metric
How to Mitigate CVE-2026-14006
Immediate Actions Required
- Update Google Chrome to version 150.0.7871.47 or later on all desktop endpoints
- Restart the browser after applying the update to ensure the patched binaries are loaded
- Push the update through enterprise management tooling to reduce time-to-patch across managed devices
Patch Information
Google addressed the vulnerability in Chrome stable channel release 150.0.7871.47. Details are documented in the Google Chrome Update Announcement. Chromium-based browsers should adopt the corresponding upstream fix referenced in the Chromium Issue Tracker Entry.
Workarounds
- Restrict browsing to trusted sites through enterprise policy or DNS filtering until the patch is deployed
- Enforce Site Isolation and disable non-essential browser extensions that expand the attack surface
- Deploy web content filtering to block known malicious HTML delivery infrastructure
# Verify installed Chrome version on Linux
