CVE-2026-87500
Description
A flaw was found in ANGLE, a graphics engine used in Google Chrome. This vulnerability, caused by improper validation of an array index, allows a remote attacker to execute arbitrary code outside of the browser's security sandbox. Exploitation can occur when a user visits a specially crafted HTML page. This could lead to a complete compromise of the affected system.
Statement
This vulnerability is rated Critical because an unauthenticated remote attacker can escape client sandboxing boundaries to achieve arbitrary code execution on the host with user privileges. In Red Hat Enterprise Linux, this flaw primarily impacts desktop environments and applications that embed WebKitGTK for rendering web graphics. Headless server deployments without graphical interfaces or embedded browser components do not expose this attack surface under standard configurations.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
