DescriptionCVE.org

Use after free 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: Medium)

AnalysisAI

Remote code execution in Google Chrome versions prior to 149.0.7827.53 stems from a use-after-free flaw in the Media component, allowing a remote attacker who can lure a victim to a crafted HTML page to execute arbitrary code within the renderer sandbox. The high CVSS score of 8.8 reflects the severe impact triad (C:H/I:H/A:H), though exploitation requires user interaction (UI:R) and code execution is contained within Chrome's sandbox boundary. There is no public exploit identified at time of analysis, and SSVC indicates no observed exploitation.

Technical ContextAI

The vulnerability is a CWE-416 Use-After-Free in Chrome's Media subsystem, which handles audio/video decoding, playback pipelines, and media stream processing. UAF bugs occur when memory is freed but a dangling pointer is later dereferenced, enabling attackers to manipulate the freed memory region (typically via heap grooming) to control object vtables or function pointers. The Media component is a frequent source of Chromium UAF bugs due to its complex object lifecycle management across multiple threads and processes. Affected builds include Chrome desktop versions before 149.0.7827.53 across all supported platforms based on the Chromium upstream codebase.

RemediationAI

Vendor-released patch: update Google Chrome to 149.0.7827.53 or later via the stable channel, which Google rolls out automatically on browser restart; administrators in managed environments should verify deployment via group policy or MDM reporting and force restarts where update lag is observed. Reference the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html for full details. For Chromium-based browsers, apply the corresponding vendor update once published. As a temporary compensating control if patching is delayed, consider disabling autoplay media and restricting access to untrusted sites via web filtering or enterprise policy (URLBlocklist); note the trade-off that disabling media features will break legitimate video/audio sites and is impractical as a long-term mitigation.
