DescriptionCVE.org

Integer overflow in ANGLE in Google Chrome on Windows prior to 148.0.7778.168 allowed a remote attacker to perform an out of bounds memory write via a crafted HTML page. (Chromium security severity: Critical)

AnalysisAI

Out-of-bounds memory write in Google Chrome's ANGLE graphics abstraction layer on Windows before 148.0.7778.168 lets a remote attacker corrupt memory by luring a victim to a crafted HTML page, potentially leading to renderer-process code execution. Rated Critical by Chromium and scored CVSS 8.8, it requires user interaction (visiting a page) but no authentication. Currently there is no public exploit identified and the SSVC exploitation status is 'none', though the very low EPSS (0.07%) reflects newness rather than confirmed safety.

Technical ContextAI

ANGLE (Almost Native Graphics Layer Engine) is the translation layer Chrome uses to map WebGL/OpenGL ES calls onto native backends (Direct3D on Windows), so it processes untrusted graphics commands originating from web content. The root cause is CWE-472-adjacent integer overflow arithmetic (the description explicitly states an integer overflow) that miscomputes a buffer size or offset, resulting in an out-of-bounds write. Because ANGLE runs inside the sandboxed renderer on Windows, the immediate memory-corruption primitive is contained by Chrome's site isolation and sandbox, but such bugs are historically chained with sandbox escapes for full compromise. The affected CPE is cpe:2.3:a:google:chrome, i.e., the desktop Chrome browser, with the flaw specific to the Windows build per the advisory.

RemediationAI

Vendor-released patch: update Google Chrome to 148.0.7778.168 or later on Windows via the Stable channel update (http://chromereleases.googleblog.com/2026/05/stable-channel-update-for-desktop_12.html); most installations receive this automatically, so verify the version under chrome://settings/help and relaunch to apply. For Chromium-based derivatives (Edge, and Red Hat/SUSE Chromium packages noted in the tags), apply the corresponding vendor build once released. If patching must be delayed, reduce exposure by restricting untrusted browsing and, as a targeted compensating control, disabling hardware-accelerated graphics (chrome://settings 'Use graphics acceleration when available' off, or the --disable-gpu / SwiftShader fallback) to limit ANGLE's exposure to attacker-controlled GPU command paths - with the trade-off of degraded WebGL/graphics performance and increased CPU use. Enterprise policy can also enforce site isolation and block WebGL via the WebGL/3D-APIs policy to shrink the attack surface until the update is deployed.
