CVE-2026-126918
Description
A flaw was found in chromium-browser. This vulnerability exists due to a use-after-free condition in the Layout component, where the application references memory after it has been released. A remote attacker could exploit this by enticing a user to visit a specially crafted HTML page, potentially allowing arbitrary code execution within the browser's sandbox environment.
Statement
This vulnerability is rated as having Important impact because, although it allows remote code execution when a user visits a malicious webpage, execution is constrained within the browser renderer sandbox and requires user interaction. Exploitation cannot directly compromise the underlying operating system or access host resources without an accompanying sandbox escape vulnerability. Red Hat Enterprise Linux workstation deployments are primarily exposed when users interact with untrusted web content.
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.
