CVE-2026-10018 Google CVE debrief

An integer overflow vulnerability in ANGLE, the graphics layer used by Google Chrome, could allow a remote attacker to extract potentially sensitive information from process memory by tricking a user into visiting a crafted HTML page. The vulnerability was addressed in Chrome version 148.0.7778.216. The Chromium security team rated this issue as Medium severity. The underlying weakness is categorized as CWE-472 (External Control of Assumed-Immutable Web Parameter), though the primary impact stems from the integer overflow condition in the graphics processing pipeline. No evidence of active exploitation or ransomware campaign use has been identified.

Who should care

Organizations with large Chrome deployments, particularly those in sectors handling sensitive data through web applications (financial services, healthcare, government). Security teams responsible for browser security posture and patch management. End users who process untrusted web content. Developers of web-based applications relying on WebGL or GPU-accelerated rendering features.

Technical summary

The vulnerability exists in ANGLE (Almost Native Graphics Layer Engine), which translates OpenGL ES API calls to native graphics APIs. An integer overflow condition can occur during graphics processing operations, leading to out-of-bounds memory access that exposes process memory contents to attacker-controlled JavaScript or HTML content. The attack vector requires user interaction through visiting a malicious web page. Successful exploitation results in information disclosure rather than code execution, limiting immediate impact but potentially exposing session tokens, cryptographic material, or other sensitive data resident in the Chrome GPU process address space.

Defensive priority

Recommended defensive actions

  • Update Google Chrome to version 148.0.7778.216 or later to remediate this vulnerability.
  • For managed enterprise environments, prioritize deployment of the stable channel update to endpoints processing untrusted web content.
  • Consider implementing site isolation policies and restricting execution of untrusted HTML content where update deployment is delayed.
  • Monitor for anomalous GPU process crashes or unexpected memory access patterns in Chrome as potential indicators of exploitation attempts.
  • Review application logs for visits to suspicious or newly registered domains that may serve crafted HTML content targeting this vulnerability.
