CVE-2026-113227
Description
A flaw was found in chromium-browser. This flaw allows a remote attacker to achieve arbitrary code execution within the browser sandbox due to a use-after-free issue in the Editing component, where previously released memory is improperly accessed. To exploit this vulnerability, an attacker must convince a user to open a specially crafted HTML page.
Statement
This vulnerability is rated as having an Important severity for Red Hat because successful remote exploitation can result in arbitrary code execution within the confined renderer process without requiring prior authentication. Although triggering the condition requires user interaction to navigate to a malicious webpage, the potential compromise of browser session integrity and confidentiality warrants an Important rating rather than Moderate. Standard Red Hat Enterprise Linux releases do not ship Chromium in core channels, restricting potential impact primarily to workstations and community environments such as EPEL where the standalone browser package is deployed.
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.
