CVE-2026-76046
Description
A flaw was found in ANGLE, a component used in Google Chrome on Android. A remote attacker, who has already compromised the renderer process, could exploit a buffer overflow vulnerability by tricking a user into visiting a specially crafted HTML page. This could allow the attacker to execute arbitrary code outside of the browser's security sandbox, leading to a compromise of the affected system.
Statement
Red Hat rates this vulnerability as Important because an attacker can escape browser process isolation and achieve arbitrary code execution with the permissions of the local user. Although this flaw allows a sandbox escape, it is rated Important rather than Critical due to requiring user interaction to process untrusted web content alongside a previously compromised rendering engine. On Red Hat Enterprise Linux, this impact is primarily restricted to desktop environments and applications utilizing WebKitGTK, leaving default headless server installations unaffected.
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).
