CVE-2026-112997
Description
A flaw was found in chromium-browser. A remote attacker could exploit a memory corruption issue in the Cascading Style Sheets (CSS) engine by enticing a user to load a specially crafted HTML page. Successful exploitation could allow the attacker to execute arbitrary code within the browser's sandbox environment.
Statement
This vulnerability is rated as an Important impact because an unauthenticated remote attacker can execute arbitrary code within the browser sandbox if an end user visits a malicious website. Red Hat Enterprise Linux does not include Chromium in core repositories, limiting exposure to systems where community packages from Fedora or EPEL have been explicitly installed. Although default sandbox boundaries prevent direct host compromise, the capability to achieve remote code execution inside the renderer process justifies the Important rating over Moderate.
Understanding the Weakness (CWE)
Integrity
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands

Availability
Technical Impact: DoS: Crash, Exit, or Restart
Attempting to access out-of-range, invalid, or unauthorized memory could cause the product to crash.
Other
