CVE-2026-126870
Description
A flaw was found in the ANGLE component of chromium-browser. A remote attacker could trigger this issue by convincing a user to visit a specially crafted HTML page, leading to information disclosure. Due to an uninitialized resource handling error, this vulnerability allows the attacker to read memory outside the browser's security sandbox.
Statement
This vulnerability is rated as Important severity because successful exploitation allows an attacker to escape sandbox boundaries and expose sensitive process memory, elevating the confidentiality risk beyond typical browser-level isolation. In Red Hat Enterprise Linux environments, chromium-browser is primarily used in graphical workstation deployments where processing web content is user-initiated. Exploitation requires user interaction, specifically convincing a user to navigate to a malicious web page, preventing automated or unassisted remote attacks.
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; Read Application Data
When reusing a resource such as memory or a program variable, the original contents may not have been cleared before it is sent to an untrusted party.
Availability
Technical Impact: DoS: Crash, Exit, or Restart; DoS: Instability
The uninitialized resource may contain values that cause program flow to change in ways that the programmer did not intend, possibly leading to a crash.
Other
Technical Impact: Unexpected State; Varies by Context
The consequences vary depending on the type of resource and how it is used within the product.
