DescriptionCVE.org

Inappropriate implementation in GPU in Google Chrome prior to 149.0.7827.53 allowed a remote attacker to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: Critical)

AnalysisAI

Sandbox escape in Google Chrome's GPU component prior to version 149.0.7827.53 allows remote attackers to break out of the renderer sandbox via a crafted HTML page when a user visits a malicious site. Google's Chromium team rated the underlying issue Critical severity, and while a patch is available, no public exploit identified at time of analysis and EPSS estimates exploitation probability at only 0.03%.

Technical ContextAI

The flaw resides in Chrome's GPU process, which handles hardware-accelerated rendering, WebGL, WebGPU, and compositing on behalf of sandboxed renderer processes. The CWE-787 classification (out-of-bounds write) combined with the 'Buffer Overflow, Memory Corruption' tags indicates the 'inappropriate implementation' is a memory-safety defect in GPU command handling - a historically high-value target because the GPU process runs with broader privileges than the renderer sandbox, making it a common pivot for sandbox escapes. Affected builds are Chrome desktop prior to 149.0.7827.53 across the Stable channel.

RemediationAI

Vendor-released patch: Chrome 149.0.7827.53 - update all desktop Chrome installations to 149.0.7827.53 or later via the Stable channel update described at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html, and ensure managed fleets force a browser relaunch so the new binary is actually loaded. Embedders and Chromium-derived browsers (Edge, Brave, Opera, Vivaldi, Electron) should pick up the corresponding upstream fix from their vendors once published. If patching must be delayed, compensating controls include disabling hardware acceleration in chrome://settings (which reduces the GPU process attack surface but degrades video, WebGL, and WebGPU performance and breaks some sites), enforcing Site Isolation and restricting WebGL/WebGPU via enterprise policy (HardwareAccelerationModeEnabled=false, WebGLEnabled=false), and blocking untrusted browsing through proxy-level URL filtering - each trades user experience or productivity for reduced exposure.
