Published: 02 December 2025
Description
Adversaries may exploit software vulnerabilities in client applications to execute code.
Security Summary
CVE-2025-13633 is a use-after-free vulnerability (CWE-416) in the Digital Credentials component of Google Chrome prior to version 143.0.7499.41. The flaw enables a remote attacker who has compromised the renderer process to potentially exploit heap corruption via a crafted HTML page. Chromium security rates it as High severity, with a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).
A remote attacker can exploit this vulnerability over the network with low attack complexity and no privileges required, though user interaction is necessary, such as rendering a malicious HTML page in the browser. Assuming prior compromise of the renderer process, successful exploitation leads to heap corruption, enabling high-impact effects on confidentiality, integrity, and availability.
Google's Chrome stable channel update to version 143.0.7499.41 and later addresses the issue, as detailed in the Chrome Releases blog post at https://chromereleases.googleblog.com/2025/12/stable-channel-update-for-desktop.html and Chromium issue tracker entry at https://issues.chromium.org/issues/458082926. Security practitioners should prioritize updating affected Chrome installations.
