Out of bounds read and write in ANGLE 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 ANGLE graphics layer prior to version 149.0.7827.53 allows a remote attacker to trigger an out-of-bounds read and write via a crafted HTML page, with a CVSS 9.6 reflecting scope change and high impact across confidentiality, integrity, and availability. The flaw was rated Critical internally by Chromium and reported by Google's own CVE admin team; no public exploit identified at time of analysis, and CISA SSVC currently lists exploitation status as none.
Technical ContextAI
ANGLE (Almost Native Graphics Layer Engine) is the translation layer Chrome uses to convert OpenGL ES API calls into the underlying platform graphics API (Direct3D on Windows, Metal on macOS, Vulkan/GL on Linux/Android), and is reachable from web content through WebGL and WebGPU. The CWE-125 root cause (out-of-bounds read) combined with an out-of-bounds write - as noted in the description and reinforced by the 'Buffer Overflow' and 'Information Disclosure' tags - typically arises from missing or incorrect bounds checking when parsing shader inputs, vertex buffers, or texture parameters supplied by attacker-controlled JavaScript. Because ANGLE code runs inside the GPU process, memory corruption there is a well-known path to escaping Chrome's renderer sandbox by exploiting the more privileged GPU process boundary.
RemediationAI
Upgrade Google Chrome to the vendor-released patch version 149.0.7827.53 or later on all desktop platforms, as published in the Chrome stable channel update advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html; the Chromium issue tracker entry (https://issues.chromium.org/issues/498904293) is referenced but access is typically restricted until further disclosure. As compensating controls until patching completes, administrators can disable hardware-accelerated graphics via the 'HardwareAccelerationModeEnabled' enterprise policy (which forces software rasterization and largely sidesteps ANGLE/WebGL code paths, at a noticeable performance cost for video, canvas, and WebGL workloads), or block WebGL/WebGPU via site-isolation and content policies for high-risk user populations (which will break legitimate 3D, mapping, and ML-in-browser features). Downstream Chromium-based browsers should be updated as their vendors ship the merged fix.
