Type Confusion in Media in Google Chrome prior to 149.0.7827.53 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Remote code execution in Google Chrome before 149.0.7827.53 allows a remote attacker to execute arbitrary code inside the renderer sandbox by luring a user to a crafted HTML page that triggers a type confusion in the Media component. The flaw carries a CVSS 8.8 (High) rating and requires user interaction (visiting a page), and while no public exploit has been identified at time of analysis, Chromium-rated High Media bugs have historically been chained with sandbox escapes for full compromise.
Technical ContextAI
The vulnerability is a CWE-843 (Access of Resource Using Incompatible Type, or 'type confusion') flaw in Chrome's Media subsystem, which handles parsing and playback of audio/video content embedded in HTML pages. Type confusion occurs when code interprets memory as one object type while it actually holds another, enabling attackers to read or write outside the intended object layout and ultimately hijack control flow. Chromium's Media stack processes complex container/codec data from the network, making it a frequently targeted attack surface; exploitation here yields code execution within the renderer sandbox process per the advisory wording.
RemediationAI
Vendor-released patch: update Google Chrome to 149.0.7827.53 or later on all desktop platforms via the Stable channel auto-updater, then restart the browser to load the new binary (auto-update will not apply until the process restarts). The vendor advisory is https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html. Enterprise fleets should push the update via Chrome Browser Cloud Management or their endpoint management system and verify chrome://version on a sample of hosts. If patching must be delayed, compensating controls include disabling autoplay and using the SitePerProcess and StrictOriginIsolation enterprise policies to harden the renderer sandbox boundary, blocking access to untrusted sites via web proxy/DNS filtering, and instructing users to avoid clicking unsolicited links - trade-offs are user friction and incomplete coverage, since any HTML page rendered (including ads) can deliver the exploit. Users of Chromium-based browsers (Edge, Brave, Opera, Vivaldi) should update once their vendor ships the merged fix.
