CVE-2026-79230
Description
A flaw was found in ANGLE, a component of Google Chrome. Improper input validation could allow a remote attacker to execute arbitrary code outside of the browser's security sandbox by enticing a user to visit a specially crafted HTML page. This could lead to a complete compromise of the affected system.
Statement
This vulnerability is rated as having Critical impact for Red Hat products because a remote, unauthenticated attacker could escape the client sandbox and execute arbitrary instructions on the host environment. In Red Hat Enterprise Linux, the affected ANGLE graphics translation layer is integrated into the WebKitGTK (webkit2gtk3) library, which powers local desktop and rendering utilities. Successful exploitation depends on an interactive user loading malicious web content, meaning server installations operating without graphical components are not exposed.
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).
