Use after free in Views in Google Chrome prior to 148.0.7778.96 allowed an attacker who convinced a user to install a malicious extension to execute arbitrary code via a crafted Chrome Extension. (Chromium security severity: Medium)

AnalysisAI

Remote code execution in Google Chrome versions prior to 148.0.7778.96 via malicious extension exploitation of use-after-free in Views component. Successful exploitation requires convincing a user to install a crafted Chrome extension, after which the attacker can execute arbitrary code with Chrome's privileges. Google has released Chrome 148.0.7778.96 to address this vulnerability. No evidence of active exploitation (not listed in CISA KEV) or public proof-of-concept code identified at time of analysis. CVSS 7.5 severity driven by high attack complexity and required user interaction, which moderates real-world exploitation risk despite potential for full system compromise.

Technical ContextAI

This vulnerability stems from a use-after-free (CWE-416) memory corruption flaw in Chrome's Views UI framework, which handles user interface components and rendering. Use-after-free vulnerabilities occur when code attempts to access memory that has already been deallocated, creating opportunities for attackers to control the freed memory region and redirect program execution. In this case, the flaw can be triggered through Chrome's extension API, allowing malicious extensions to manipulate the Views component's memory lifecycle. The affected product CPE (cpe:2.3:a:google:chrome) indicates all Chrome installations across Windows, macOS, and Linux platforms are vulnerable prior to version 148.0.7778.96. The extension delivery vector is significant because Chrome's extension permissions model can grant extensive access to browser internals, making this a particularly effective attack surface once the initial social engineering succeeds.

RemediationAI

Update Google Chrome to version 148.0.7778.96 or later immediately through Chrome's built-in update mechanism (Settings > About Chrome) or by downloading from google.com/chrome. Chrome typically auto-updates within 24-48 hours, but manual update verification is recommended for critical systems. For enterprise deployments, push Chrome 148.0.7778.96 via group policy or endpoint management tools. Interim compensating controls include: (1) Restricting extension installation to admin-approved Chrome Web Store items only via ExtensionInstallBlocklist and ExtensionInstallAllowlist policies, which prevents installation of malicious extensions but may impact productivity for users requiring custom extensions; (2) Disabling developer mode extensions entirely via DeveloperToolsAvailability policy, which blocks sideloading vectors but prevents legitimate development work; (3) Implementing enhanced user awareness training focused on extension permission requests, particularly those requesting broad host permissions or access to sensitive browser APIs, though this relies on user judgment and is not technically preventative.
