MITRE ATT&CK
2 techniques across 2 tactics: Execution, Privilege Escalation The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | The victim must visit or open a crafted HTML page in Google Chrome on Android versions prior to 146.0.7680.153. Requires user interaction (opening the malicious webpage). Remote unauthenticated attacker can deliver the exploit. |
| Impact | This vulnerability presents critical real-world risk despite the absence of a CVSS vector in the provided data. The Chromium severity designation of Critical, combined with the sandbox escape capability, indicates high technical impact and likely low attack complexity (attackers need only trick a user into visiting a malicious webpage). The availability of a vendor patch and tracking in the Debian ecosystem (9 releases) suggest this is a known, disclosed vulnerability with institutional awareness. The attack vector is Network-based (remote via crafted HTML), requiring no special privileges or user interaction beyond normal browsing. Without explicit EPSS or KEV status in the provided intelligence, the real-world exploitation probability cannot be directly quantified, but the sandbox escape potential and Critical rating strongly suggest this should be prioritized for immediate patching. The absence of POC confirmation in available references does not diminish the urgency, as sandbox escape vulnerabilities are often weaponized quickly. |
| Exploit ScenarioDerived | An attacker hosts a malicious website containing a crafted HTML page with specially constructed WebGL code that triggers an out-of-bounds memory read or write in Chrome's graphics processing stack. When an unsuspecting Android user visits this website via Chrome, the WebGL payload executes within the browser's rendering process, exploiting the memory safety flaw to gain write access to critical memory regions. By chaining this memory corruption with other browser internals, the attacker achieves sandbox escape, breaking out of Chrome's security sandbox to execute arbitrary native code on the Android device with Chrome's process privileges. |

Alert meAnalysisAIv1 – Mar 20, 2026
Out-of-bounds memory corruption in Google Chrome's WebGL implementation on Android prior to version 146.0.7680.153 enables remote attackers to escape the browser sandbox by delivering a malicious HTML page, requiring only user interaction. This critical vulnerability affects Chrome users on Android devices and could lead to complete system compromise if successfully exploited. A patch is available in Chrome 146.0.7680.153 and later versions.
Earlier versions of this analysis (1)
An out-of-bounds memory access vulnerability exists in the WebGL implementation of Google Chrome on Android versions prior to 146.0.7680.153. A remote attacker can exploit this vulnerability by crafting a malicious HTML page to trigger the memory access flaw, potentially achieving sandbox escape and executing arbitrary code with elevated privileges. The vulnerability is classified as Critical by Chromium security standards and a patch is available from the vendor.
RemediationAI
Immediately upgrade Google Chrome on Android to version 146.0.7680.153 or later via the Google Play Store; the patch is available from the vendor as documented in the stable channel update (chromereleases.googleblog.com/2026/03/stable-channel-update-for-desktop_18.html). For enterprise deployments using Debian packages, update all 9 affected releases to patched versions available through the Debian security repository. Until patching is completed, users should avoid visiting untrusted websites and consider disabling WebGL in browser settings if feasible; however, this may degrade functionality for legitimate 3D web applications. Monitor the official Chromium bug tracker (issues.chromium.org/issues/475877320) for any post-patch security analysis.

Technical ContextAI · show details
This vulnerability resides in WebGL, a JavaScript API for rendering interactive 3D graphics within web browsers, which operates at a lower level of system abstraction than typical web content. The out-of-bounds memory access (CWE category: Memory Safety) indicates improper bounds checking when WebGL processes graphics commands or accesses memory buffers, allowing an attacker to read or write beyond allocated memory regions. WebGL on Android uses native GPU drivers and browser-level graphics processing, making it a particularly sensitive attack surface for sandbox escape scenarios. The vulnerability affects Chrome 146.0.7680.153 and earlier versions on Android, as confirmed by the ENISA EUVD tracking (EUVD-2026-13445) and Chromium issue tracker (issues.chromium.org/issues/475877320).

Out of bounds memory access in WebGL in Google Chrome on Android prior to 146.0.7680.153 allowed a remote attacker to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: Critical)
Executive ViewAI
Organizations using WebGL in Google Chrome on Android face significant risk from CVE-2026-4439, a out-of-bounds write vulnerability rated CVSS 8.8. Exploitation could allow attackers to corrupt memory, crash the application, or potentially execute arbitrary code. A patch is available and should be applied as part of regular vulnerability management.
Apply vendor patch. If immediate patching is not feasible: (1) Enable ASLR and DEP where available; (2) Implement network segmentation; (3) Monitor for exploitation indicators.

SSVC AssessmentENISA
Priority Score
Attack Technique
A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.
Memory corruption occurs when a program writes data beyond the boundaries of allocated memory regions or accesses memory in unintended ways, violating the integrity of the process's address space.
