CVE-2026-126868
Description
A flaw was found in chromium-browser. A type confusion vulnerability in the V8 JavaScript engine allows a remote attacker to potentially execute arbitrary code within the browser sandbox. By convincing a user to visit a specially crafted HTML page, the attacker can exploit memory corruption to compromise the browser process.
Statement
This vulnerability is rated as an Important severity flaw because an unauthenticated remote attacker can trigger memory corruption leading to code execution within the renderer process by tricking a user into rendering malicious web content. While execution is typically restricted by the browser's multi-process sandbox, compromise of the rendering engine allows unauthorized access to sensitive browsing session data and provides an initial foothold. Red Hat Enterprise Linux systems deploying Chromium as a desktop browser are susceptible when users navigate to untrusted websites.
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)
Other
Technical Impact: Varies by Context
When the product accesses the resource using an incompatible type, this could trigger logical errors because the resource does not have expected properties.
Availability,Integrity,Confidentiality
Technical Impact: Read Memory; Modify Memory; Execute Unauthorized Code or Commands; DoS: Crash, Exit, or Restart
If a memory buffer is accessed using an incompatible type, and the allocated buffer is smaller than the type that the code is attempting to access, then an attacker could read or write memory outside the bounds of the buffer, leading to a crash or possibly code execution.
