Use after free in WebView in Google Chrome on Android prior to 146.0.7680.178 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Use-after-free in Chrome's WebView on Android prior to version 146.0.7680.178 allows a remote attacker with a compromised renderer process to escape the sandbox via crafted HTML, potentially leading to arbitrary code execution outside the browser's security boundary. This vulnerability requires prior renderer compromise but eliminates a critical containment layer, classified as High severity by Chromium.
Technical ContextAI
The vulnerability exists in WebView's memory management within Google Chrome's rendering engine on Android. CWE-416 (use-after-free) occurs when code attempts to access memory that has been deallocated, allowing attackers to either corrupt heap state or execute arbitrary code if the freed memory is reallocated with attacker-controlled data. In this case, the flaw specifically affects the WebView component (cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:*), which is a critical sandboxing boundary in Android's security model. The sandbox escape vector indicates the vulnerability allows breaking out from the renderer process's restricted execution environment, a significant escalation from web content compromise to system-level impact.
RemediationAI
Vendor-released patch: Update Google Chrome on Android to version 146.0.7680.178 or later. This update is available through the Google Play Store and will be automatically deployed to most Android users with auto-update enabled. Organizations managing Chrome deployments should prioritize this update, particularly for devices that may be targeted by advanced attackers, as the sandbox escape capability represents a critical escalation vector.
