DescriptionCVE.org

Use after free in Oilpan 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

Arbitrary code execution in Google Chrome desktop versions prior to 150.0.7871.47 stems from a use-after-free in Oilpan, Blink's garbage collector, letting a remote attacker who lures a victim to a crafted HTML page run code within the renderer sandbox. Google rated it Medium severity; there is no public exploit identified at time of analysis and EPSS exploitation probability is low (0.26%, 17th percentile). Google has shipped a fixed Stable-channel build, and exploitation requires user interaction (visiting a malicious page).

Technical ContextAI

The flaw is a CWE-416 use-after-free in Oilpan, the C++ garbage-collected heap manager used by Chromium's Blink rendering engine. Oilpan tracks lifetimes of DOM and rendering objects; a use-after-free occurs when a pointer to a freed heap object is subsequently dereferenced, allowing an attacker who controls page content (HTML/JS) to groom the heap, reclaim the freed allocation with attacker-controlled data, and hijack control flow. The affected component (cpe:2.3:a:google:chrome) is the browser renderer process, so successful exploitation yields code execution confined to the renderer sandbox unless separately chained with a sandbox escape.

RemediationAI

Vendor-released patch: update Google Chrome to 150.0.7871.47 or later on all desktop platforms; Chrome auto-updates, so ensure the browser is fully closed and relaunched to apply the update, and verify via chrome://settings/help. Enterprises managing Chrome via policy should push the fixed build through their update infrastructure and confirm client versions. Downstream Chromium repackagers (e.g., SUSE) should apply their vendor's corresponding patched package once released. Reference the vendor advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html. As an interim compensating control if patching is delayed, restrict browsing to trusted sites and consider enabling Chrome's Site Isolation (default on) plus stricter enterprise policies limiting untrusted script - with the trade-off of reduced usability; note that disabling JavaScript would significantly break most modern sites and is generally impractical.
