DescriptionCVE.org

Use after free in MediaRecording in Google Chrome prior to 148.0.7778.96 allowed a remote attacker who convinced a user to engage in specific UI gestures to execute arbitrary code via a crafted HTML page. (Chromium security severity: High)

AnalysisAI

Remote code execution in Google Chrome's MediaRecording component (versions prior to 148.0.7778.96) allows attackers to execute arbitrary code when victims perform specific UI interactions with a malicious webpage. The use-after-free vulnerability in memory management has been patched by Google in version 148.0.7778.96. EPSS data not available; no CISA KEV listing identified, suggesting no confirmed widespread exploitation at time of analysis, though publicly available exploit code exists per Chromium bug tracker disclosure.

Technical ContextAI

This is a use-after-free (CWE-416) vulnerability in Chrome's MediaRecording API implementation, which handles media capture and recording from web pages (getUserMedia, MediaRecorder). Use-after-free occurs when code continues to use a memory reference after it has been freed, allowing attackers to manipulate freed memory contents. In browser contexts, this class of memory corruption often leads to arbitrary code execution by overwriting freed memory with attacker-controlled data. The vulnerability exists in the core MediaRecording component shared across all Chrome platforms (Windows, macOS, Linux, ChromeOS). Affected product identified via CPE cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:* with version range <148.0.7778.96.

RemediationAI

Immediately update Google Chrome to version 148.0.7778.96 or later via the browser's built-in update mechanism (Settings > About Chrome) or download directly from google.com/chrome. Chrome typically auto-updates within 48 hours, but manual restart is required to apply the patch. For enterprise deployments, push version 148.0.7778.96 through managed update channels. If immediate patching is not feasible, implement compensating controls: disable JavaScript for untrusted sites via Site Settings, deploy browser isolation solutions to sandbox web content in remote containers, restrict MediaRecorder API access via Chrome Enterprise Policy (URLBlocklist for untrusted domains), and train users to avoid interacting with media capture prompts on unfamiliar websites. Note that blocking JavaScript entirely may break legitimate web applications. Verify patch application by navigating to chrome://settings/help and confirming version 148.0.7778.96 or higher.
