Use after free in GFX in Google Chrome on Linux prior to 149.0.7827.53 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: Critical)

AnalysisAI

Heap corruption in Google Chrome's GFX component on Linux prior to version 149.0.7827.53 allows remote attackers to potentially achieve code execution when a victim visits a crafted HTML page. Google rates the underlying Chromium issue as Critical severity, and a vendor patch is available; no public exploit identified at time of analysis.

Technical ContextAI

The flaw is a CWE-416 Use-After-Free in Chrome's GFX subsystem, which handles graphics primitives (rasterization, image decoding, and compositing) within the renderer process. Use-after-free bugs occur when a pointer to a freed heap object is dereferenced, enabling an attacker who can groom the heap (e.g., via JavaScript-allocated objects) to coerce the dangling pointer to reference attacker-controlled data and corrupt control-flow or virtual table pointers. The affected platform identified in the description is Linux desktop builds of Chrome, with the fix landing in stable channel build 149.0.7827.53.

RemediationAI

Apply the vendor-released patch by upgrading Linux Chrome to 149.0.7827.53 or later, available via Google's stable-channel update documented at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html; most installations will receive this automatically on browser restart, so users should fully close and relaunch Chrome to ensure the new binary is loaded. As compensating controls until patching completes, restrict browsing to trusted sites via enterprise policy (URLBlocklist/URLAllowlist), enforce Site Isolation (already default but verify chrome://flags), and consider disabling hardware-accelerated graphics via the --disable-gpu flag or chrome://settings - note this degrades video and canvas performance and breaks WebGL-dependent applications. Organizations using Chromium-based browsers (Edge, Brave, Opera, Electron apps) should track their respective vendor advisories for the corresponding fix uptake.
