CVE-2026-14005: Use-After-Free in Chrome Android Omnibox – Patch Guidance

Technical summary

CVE-2026-14005 is a use-after-free vulnerability (CWE-416) in the Omnibox component of Chromium on Android. The flaw allows a remote attacker to trigger heap corruption by delivering a specially crafted HTML page to a target who performs certain UI gestures. The vulnerability stems from improper memory management in the address bar UI, where freed memory regions are accessed under specific interaction conditions. Google assigned it a Medium severity rating within the Chromium security classification, though the CVSS 3.1 score of 8.8 reflects HIGH severity due to the network attack vector, low complexity, lack of privilege requirements, and impact to confidentiality, integrity, and availability.

Business impact

This vulnerability poses a significant risk to Android users who rely on Chrome for browsing. Successful exploitation could result in arbitrary code execution within the Chrome process, potentially allowing attackers to steal sensitive data, install malware, or compromise device security. Organizations deploying Chrome on corporate Android devices face elevated risk of data exfiltration and credential theft. The attack requires minimal attacker sophistication—only crafted webpage delivery and user interaction—making it a practical threat in both targeted and opportunistic attack scenarios.

Affected systems

Google Chrome on Android versions prior to 150.0.7871.47 are affected. The vulnerability is specific to the Android platform and does not affect Chrome on Windows, macOS, Linux, or iOS based on the description provided. Organizations and users with unpatched Chrome installations on Android devices are at risk. The broader Android ecosystem is indirectly affected as compromised Chrome instances could be leveraged for further device compromise.

Exploitability

Exploitability is moderate to high. The attack requires a remote attacker to distribute a malicious webpage and convince a user to visit it and perform specific UI gestures with the Omnibox (address bar). While this requires user interaction, it is a lower bar than many exploits—users routinely interact with address bars and may not recognize malicious intent. No privileged access or complex social engineering is required beyond typical phishing or watering-hole tactics. The attack surface is broad given Chrome's ubiquity on Android.

Remediation

Users and administrators should immediately update Chrome on Android to version 150.0.7871.47 or later. Check the Google Play Store for the latest Chrome update and ensure automatic updates are enabled. Organizations managing Android devices through MDM/EMM solutions should prioritize Chrome patch deployment. There are no known workarounds; patching is the only mitigation. Verify update completion by checking Settings > About Chrome in the browser.

Patch guidance

Update Chrome to version 150.0.7871.47 or later. On most Android devices, open the Google Play Store, search for Chrome, and tap 'Update' if available. Enable automatic updates in Google Play settings to prevent future delays. Enterprise administrators can enforce updates via Android Device Administrator or Google Play for Work policies. Verify patch application by navigating to Chrome's About page, which will display the installed version. If the version number remains below 150.0.7871.47 after attempting an update, contact Google Support or your device manufacturer for assistance.

Detection guidance

Monitor Chrome crash logs and system logs for unusual Omnibox-related exceptions or segmentation faults, which may indicate exploitation attempts. Look for unexpected process terminations or system instability following visits to suspicious websites. Detect user visits to potentially malicious webpages using network proxies or DNS filtering—exploit delivery requires the user to visit an attacker-controlled or compromised website. On the endpoint, monitor for Chrome child process spawning anomalies or unexpected elevated privilege requests post-exploitation. EDR tools should alert on heap corruption indicators or Chrome security sandbox breakout attempts.

Why prioritize this

This vulnerability merits immediate prioritization due to its HIGH CVSS score (8.8), remote attack vector, low attack complexity, and lack of privilege requirements. The practical exploitability—requiring only webpage delivery and user interaction—combined with potential for full code execution makes it a priority 1 issue. Android's large user base and Chrome's dominance as the default browser increase exposure. Organizations should treat this as a critical patch within 72 hours of verification.

Risk score, explained

The CVSS 3.1 score of 8.8 (HIGH) reflects a network-based attack vector (AV:N) requiring minimal attacker capability (AC:L), no prior authentication (PR:N), and user interaction (UI:R). The impact is severe across all three security dimensions: confidentiality (C:H) due to potential data exfiltration, integrity (I:H) from code execution capability, and availability (A:H) from process compromise or system instability. The vulnerability does not break the security boundary between Chrome and the OS (S:U), but the consequences within the browser context are substantial. The score appropriately reflects the combination of ease of exploitation and severity of potential impact.
