CVE-2026-126842

Description

A flaw was found in the ANGLE component of Chromium. A remote attacker could exploit this vulnerability to execute arbitrary code outside the browser sandbox. By convincing a user to view a specially crafted HTML page, the attacker triggers a use-after-free condition in the graphics engine.

Statement

Red Hat Product Security rates this vulnerability as Important because successful exploitation allows a remote attacker to break out of the browser sandbox and run arbitrary commands with the privileges of the active user. Although triggering the condition requires social engineering to trick a user into visiting an untrusted site, escaping renderer containment represents a serious compromise of host boundaries. Server deployments and systems without interactive graphical browser usage are not exposed to this issue.

Mitigation

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.

Understanding the Weakness (CWE)

Confidentiality

Technical Impact: Read Memory

If the expired pointer is used in a read operation, an attacker might be able to control data read in by the application.

Availability

Technical Impact: DoS: Crash, Exit, or Restart

If the expired pointer references a memory location that is not accessible to the product, or points to a location that is "malformed" (such as NULL) or larger than expected by a read or write operation, then a crash may occur.

Integrity,Confidentiality,Availability

Technical Impact: Execute Unauthorized Code or Commands

If the expired pointer is used in a function call, or points to unexpected data in a write operation, then code execution may be possible.
