CVE-2026-13831 is a use-after-free vulnerability in the GPU subsystem of Google Chrome versions prior to 150.0.7871.47. It involves out of bounds read and write operations that can be exploited by a remote attacker who has already compromised the renderer process. Exploitation allows arbitrary code execution within the sandbox environment via a crafted HTML page. The vulnerability is recognized as high severity by Chromium security. The vendor advisory is published but does not explicitly state the patch status in the provided data.

Successful exploitation could allow an attacker with control over the renderer process to execute arbitrary code inside the sandbox, potentially leading to further compromise of the affected system. The vulnerability affects the GPU component and involves memory corruption (use-after-free), which can be leveraged for code execution.

The vendor advisory link provided should be consulted for the latest remediation guidance. The vulnerability affects versions prior to 150.0.7871.47, indicating that updating to version 150.0.7871.47 or later likely addresses the issue. Patch status is not explicitly confirmed in the provided data; therefore, users should verify the update status via the official Google Chrome release notes or security advisories. No additional mitigation steps are specified in the available information.
