CVE-2026-14067 Overview
CVE-2026-14067 is a use-after-free vulnerability in Chrome for iOS affecting Google Chrome versions prior to 150.0.7871.47. A remote attacker can execute arbitrary code by convincing a user to visit a crafted HTML page. The flaw is tracked under CWE-416 and requires user interaction to trigger. Google classifies the Chromium security severity as Low, but the CVSS assessment places the vulnerability in the high range due to the potential for arbitrary code execution on the mobile browser.
Critical Impact
Successful exploitation allows arbitrary code execution in the Chrome for iOS process context via a malicious web page, compromising confidentiality, integrity, and availability of user data handled by the browser.
Affected Products
- Google Chrome for iOS versions prior to 150.0.7871.47
- Apple iPhone OS (as the underlying platform for Chrome for iOS)
- Deployments relying on Chrome for iOS for web browsing on managed Apple devices

Technical Details for CVE-2026-14067
Vulnerability Analysis
The vulnerability is a use-after-free condition within Chrome for iOS. Use-after-free flaws occur when a program continues to reference memory after it has been freed, allowing attackers to place attacker-controlled data into the reused allocation. When the dangling pointer is later dereferenced, the browser may execute attacker-influenced code paths.
In this case, a crafted HTML page triggers the freed-object access inside the Chrome for iOS process. Because the attack vector is the network and user interaction is required, exploitation typically involves luring the target to a malicious URL or embedding a hostile resource within a compromised site. Successful exploitation yields arbitrary code execution within the browser sandbox on iOS.
Root Cause
The root cause is improper object lifetime management in Chrome for iOS code that handles web content rendering. An object is freed while a reference to it remains reachable through another code path. Subsequent operations on the stale reference lead to memory corruption. This class of bug is tracked as CWE-416: Use After Free.
Attack Vector
An attacker hosts or injects a crafted HTML page. When a victim using a vulnerable Chrome for iOS build loads the page, the parser or renderer triggers the use-after-free condition. The attacker then manipulates heap layout to control the contents of the reallocated memory and hijack execution flow.
No verified public proof-of-concept has been released. Refer to the Chromium Issue Tracker Entry and the Google Chrome Stable Update advisory for vendor-provided technical context.
Detection Methods for CVE-2026-14067
Indicators of Compromise
- Chrome for iOS clients reporting version strings below 150.0.7871.47 in device inventory or MDM telemetry.
- Browser crash reports referencing renderer or WebKit-backed process termination shortly after loading external content.
- Outbound connections from mobile endpoints to newly registered or low-reputation domains hosting HTML payloads.
Detection Strategies
- Correlate mobile device management (MDM) inventory data with the fixed Chrome for iOS build number to identify vulnerable installations.
- Inspect web proxy and DNS logs for user navigation to suspicious URLs preceding Chrome crash events on iOS devices.
- Alert on repeated Chrome process crashes on the same iOS device within a short interval, which can indicate exploitation attempts.
Monitoring Recommendations
- Track Chrome for iOS version distribution across the fleet using MDM reporting to measure patch coverage.
- Ingest mobile browser telemetry and network logs into a centralized analytics platform for correlation.
- Monitor threat intelligence feeds for public disclosure of exploitation activity linked to CVE-2026-14067.
How to Mitigate CVE-2026-14067
Immediate Actions Required
- Update Chrome for iOS to version 150.0.7871.47 or later through the Apple App Store on all managed and personal devices.
- Enforce automatic app updates for Chrome via MDM policy on supervised iOS devices.
- Communicate the risk to end users and instruct them to avoid untrusted links until patching is confirmed.
Patch Information
Google addressed the vulnerability in Chrome for iOS 150.0.7871.47. See the Google Chrome Stable Update release notes and the Chromium Issue Tracker Entry for additional details. Apply the update through the App Store or via MDM-managed app distribution.
Workarounds
- Use an alternate, fully patched browser on iOS until Chrome for iOS is updated.
- Restrict browsing on managed iOS devices to allowlisted, trusted domains through network filtering.
- Deploy secure web gateway policies to block access to known malicious URLs and newly observed suspicious domains.
