DescriptionCVE.org

Use after free in HTML in Google Chrome prior to 150.0.7871.47 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 prior to 150.0.7871.47 stems from a use-after-free (CWE-416) in the browser's HTML handling, letting a remote attacker who lures a victim to a crafted page execute arbitrary code, though execution is confined inside Chrome's renderer sandbox. Chromium rated the issue Medium severity precisely because the code runs within the sandbox rather than escaping it; no public exploit identified at time of analysis, and EPSS is low at 0.27% (18th percentile) with SSVC exploitation status 'none'. Google has shipped a fixed Stable-channel build.

Technical ContextAI

The flaw is a use-after-free (CWE-416) in Chrome's HTML processing path, part of the Blink rendering engine that parses and renders HTML/DOM content. Use-after-free bugs occur when a pointer to freed heap memory is dereferenced or reused, allowing an attacker who controls heap layout to place attacker-influenced data where the freed object was, leading to memory corruption and, when weaponized, control-flow hijacking. The affected component is the Chromium renderer process, which is isolated in an OS-level sandbox; per the description the resulting arbitrary code execution occurs 'inside a sandbox,' meaning it grants control of the renderer process but not, by itself, the host operating system. The CPE cpe:2.3:a:google:chrome covers the desktop browser across platforms.

RemediationAI

Vendor-released patch: update Google Chrome to 150.0.7871.47 or later via the Stable channel, per the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html; relaunch the browser to apply the update since Chrome staging alone does not complete the fix. In managed environments, push the update through enterprise policy or your patch-management tooling and verify chrome://settings/help shows the fixed build. Users of Chromium-based browsers should apply their vendor's corresponding update once it merges the upstream fix. As an interim compensating control before patching, ensure the site-isolation and renderer sandbox remain enabled (do not launch with --no-sandbox), and consider restricting exposure to untrusted web content; note this does not remove the vulnerability and only limits blast radius.
