Out of bounds read in Media in Google Chrome prior to 147.0.7727.101 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
Out-of-bounds read in Google Chrome's media component (versions prior to 147.0.7727.101) enables remote code execution when attackers convince users to perform specific UI interactions on a malicious HTML page. Google rated this high severity and released Chrome 147.0.7727.101 as a fix. No active exploitation confirmed via CISA KEV at time of analysis, though CVSS 7.5 reflects significant impact if user interaction prerequisite is met. The UI gesture requirement and high attack complexity (AC:H) reduce automated exploitation risk compared to interaction-free vulnerabilities.
Technical ContextAI
This vulnerability is rooted in CWE-125 (Out-of-bounds Read) within Chrome's media processing subsystem, which handles video/audio rendering and codec operations. When parsing specially crafted media content embedded in HTML, the media component reads memory outside allocated buffer boundaries. Unlike typical buffer overflows that write beyond bounds, out-of-bounds reads can leak sensitive memory contents or trigger controlled crashes that enable code execution when combined with other exploitation techniques like heap spraying. The affected product per CPE is Google Chrome desktop versions (<147.0.7727.101) across Windows, macOS, and Linux platforms. Media subsystem vulnerabilities are particularly dangerous because web content routinely embeds video/audio, making the attack surface accessible via normal browsing. The Chromium bug tracker issue 497412658 contains technical details but access may be restricted until sufficient patch deployment occurs.
RemediationAI
Immediately update Google Chrome to version 147.0.7727.101 or later through the browser's built-in update mechanism (Settings > About Chrome) or via enterprise deployment tools for managed environments. Chrome's automatic update feature will deploy the patch within 24-48 hours for most users, but manual verification is recommended for critical systems. For environments unable to patch immediately, implement compensating controls: disable JavaScript execution for untrusted sites via browser policies (chrome://settings/content), deploy Content Security Policy headers blocking media sources from external domains, or restrict browsing to organizational allow-lists using Chrome Enterprise policy ChromeExtensionInstallBlocklist. Note these workarounds severely limit browser functionality and should be temporary. Organizations using Chromium-based browsers (Edge, Brave, Opera) should consult respective vendor advisories for equivalent patched versions. No configuration changes mitigate the vulnerability in unpatched Chrome-upgrade is the only complete remediation. Automated enterprise patch validation can query chrome://version to confirm deployment of 147.0.7727.101+.
