Use after free in WebView in Google Chrome on Android prior to 149.0.7827.53 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: Medium)

AnalysisAI

Heap corruption in Google Chrome for Android's WebView component prior to version 149.0.7827.53 allows remote attackers to potentially execute code or crash the browser by luring victims to a crafted HTML page. The flaw is a use-after-free (CWE-416) rated CVSS 8.8 due to network reach and high impact across confidentiality, integrity, and availability, though user interaction is required. No public exploit identified at time of analysis and EPSS exploitation probability is very low (0.03%).

Technical ContextAI

WebView is the Android system component (based on the Chromium engine) that embedded apps use to render web content in-process. A use-after-free (CWE-416) occurs when memory is freed while a dangling reference remains usable, allowing an attacker who controls subsequent heap allocations to reclaim that memory with controlled data and corrupt object layouts. In a renderer-class component like WebView, successful exploitation of such heap corruption typically enables arbitrary code execution within the renderer sandbox, with potential for further chaining to escape sandboxing. Google classifies the Chromium severity as Medium despite the NVD CVSS of 8.8, reflecting Google's internal weighting of exploitability and sandbox containment.

RemediationAI

Vendor-released patch: Chrome 149.0.7827.53 - update Google Chrome for Android and Android System WebView to 149.0.7827.53 or later via the Google Play Store, and ensure managed Android fleets receive WebView updates promptly since embedded WebViews in third-party apps inherit the vulnerable code until the system WebView is patched. Confirm the rollout details via the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html and the Chromium tracker at https://issues.chromium.org/issues/500032538. As a compensating control until updates propagate, restrict users from visiting untrusted web content in apps that embed WebView (enterprise MDM policies can block sideloaded browsers or restrict in-app browsing), and consider disabling JavaScript in custom WebView-based apps where feasible - noting this will break most modern web functionality and is only viable for narrowly scoped kiosk or single-purpose apps.
