Heap buffer overflow in ANGLE in Google Chrome on Mac prior to 146.0.7680.178 allowed a remote attacker to execute arbitrary code via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Remote code execution in ANGLE (Almost Native Graphics Layer Engine) within Google Chrome on macOS prior to version 146.0.7680.178 allows unauthenticated remote attackers to execute arbitrary code by crafting a malicious HTML page that triggers a heap buffer overflow. This vulnerability affects all Chrome versions below the patched release and poses an immediate risk to macOS users who visit compromised or malicious websites.
Technical ContextAI
ANGLE is a graphics abstraction layer used by Chrome to translate OpenGL API calls to native graphics APIs (Metal on macOS, Direct3D on Windows). A heap buffer overflow (CWE-122) in ANGLE indicates that an out-of-bounds write operation occurs on the heap during graphics processing. This typically occurs when parsing or processing malformed shader code, rendering commands, or GPU texture data without proper bounds checking. The vulnerability can be triggered through a crafted HTML page containing specially crafted WebGL or Canvas 2D graphics code that causes ANGLE to write beyond allocated heap memory, corrupting adjacent heap structures and enabling code execution. The affected CPE (cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:*) indicates all Chrome versions are potentially vulnerable up to the patched version.
RemediationAI
Vendor-released patch: Google Chrome 146.0.7680.178 or later. Users should immediately update Chrome to version 146.0.7680.178 or newer via the Chrome Settings > About Chrome menu, which will trigger an automatic update check and restart. Organizations should enforce automatic updates for Chrome or use managed deployment tools (Google Admin Console for enterprise) to push the patched version to all users. Detailed patch and technical information are available at https://chromereleases.googleblog.com/2026/03/stable-channel-update-for-desktop_31.html and https://issues.chromium.org/issues/489494022. No workarounds are available; patching is the only mitigation.
