Security Summary
CVE-2025-13638 is a use-after-free vulnerability (CWE-416) in the Media Stream component of Google Chrome prior to version 143.0.7499.41. Published on 2025-12-02, it allows a remote attacker to potentially exploit heap corruption via a crafted HTML page. Chromium rates its security severity as Low, though the CVSS v3.1 base score is 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).
A remote attacker without privileges can exploit this over the network with low attack complexity, but it requires user interaction, such as convincing the user to load a malicious HTML page. Successful exploitation could lead to heap corruption, enabling high-impact compromise of confidentiality, integrity, and availability.
Mitigation is available via the Google Chrome stable channel update for desktop to version 143.0.7499.41 or later, as announced in the Chrome Releases blog post and detailed in the associated Chromium issue tracker.
