Use after free in ANGLE in Google Chrome prior to 148.0.7778.216 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High)

AnalysisAI

Remote code execution in Google Chrome's ANGLE graphics layer prior to version 148.0.7778.216 allows attackers to run arbitrary code inside the browser sandbox when a victim visits a crafted HTML page. The flaw is a use-after-free memory corruption issue (CWE-416) reported internally by the Chrome team and rated High by Chromium; no public exploit identified at time of analysis, though Chrome UAF bugs in ANGLE are historically attractive targets and pair well with sandbox escapes.

Technical ContextAI

ANGLE (Almost Native Graphics Layer Engine) is Chrome's translation layer that maps WebGL/OpenGL ES API calls onto the host system's native graphics APIs (Direct3D on Windows, Metal on macOS, Vulkan/OpenGL on Linux). It is reachable from any web page via WebGL or WebGPU surfaces and runs inside the GPU process. CWE-416 (Use After Free) indicates that an object's memory is referenced after it has been deallocated, allowing an attacker who controls subsequent heap allocations to coerce type confusion or function-pointer hijack and gain code execution. Because the bug lives in ANGLE inside the sandboxed GPU process, exploitation yields code execution scoped to that sandbox (S:U in the CVSS vector) rather than full host compromise unless chained with a sandbox escape.

RemediationAI

Vendor-released patch: Google Chrome 148.0.7778.216 - upgrade desktop installations to this version or later via the Stable channel update referenced at https://chromereleases.googleblog.com/2026/05/stable-channel-update-for-desktop_0877304591.html and restart the browser so the new binaries are loaded. Administrators managing fleets should push the update through enterprise policy (Group Policy/Jamf/MDM) and verify chrome://version on endpoints. Until patching completes, compensating controls include disabling hardware acceleration in chrome://settings (which causes ANGLE to fall back to software rendering and may avoid the vulnerable code path, at the cost of degraded WebGL/video performance) and blocking unapproved/untrusted browsing via web proxy categorization to reduce exposure to malicious HTML pages. Downstream Chromium-based browsers (Edge, Brave, Opera, Electron apps) should be updated as soon as their vendors ship the rebased build.
