CVE-2026-9910 Google CVE debrief

CVE-2026-9910 is a high-severity out-of-bounds memory access vulnerability in ANGLE, the graphics layer used by Google Chrome. The flaw affects Chrome versions prior to 148.0.7778.216 and enables remote code execution within the browser sandbox when a user visits a malicious HTML page. ANGLE (Almost Native Graphics Layer Engine) translates OpenGL ES API calls to native graphics APIs, making this vulnerability reachable through web content that triggers graphics operations. The sandboxed execution context limits but does not eliminate the security impact, as sandbox escapes may be chained. Google released the security update on May 28, 2026, and assigned Chromium security severity High. No known exploitation in ransomware campaigns has been documented.
