CVE-2026-9940

Google · Chrome

A heap buffer overflow vulnerability in the ANGLE graphics engine of Google Chrome allows for potential memory corruption.

Executive summary

A heap buffer overflow in Google Chrome’s ANGLE component presents a significant risk for remote code execution and system compromise.

Vulnerability

The vulnerability is a heap-based buffer overflow occurring within the ANGLE graphics library. By providing specially crafted input, an attacker can overwrite adjacent memory, leading to browser crashes or arbitrary code execution.

Business impact

A heap buffer overflow is a critical vector for exploitation, often allowing attackers to bypass security mitigations and execute unauthorized commands. The CVSS score of 8.8 indicates a high probability of significant impact, including full browser compromise and potential escalation to the underlying operating system.

Remediation

Immediate Action: Deploy the latest version of Google Chrome (148 or later) across all enterprise endpoints immediately upon vendor release.

Proactive Monitoring: Monitor for unusual system activity or browser crashes that may indicate an exploitation attempt in progress.

Compensating Controls: Ensure that browser-level security features and OS-level exploit mitigations (such as ASLR and DEP) are fully enabled.

Exploitation status

Public Exploit Available: false

Analyst recommendation

Organizations should treat this vulnerability with high urgency. Patching the browser is the primary defense; ensure that automated update mechanisms are functioning correctly to minimize the window of exposure.
