Deeper analysis
CVE-2025-14765 is a use-after-free vulnerability (CWE-416) in the WebGPU component of Google Chrome prior to version 143.0.7499.147. Published on 2025-12-16, it carries 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) and is classified as High severity by Chromium security. The flaw allows potential heap corruption when processing a crafted HTML page.
A remote attacker can exploit this vulnerability by luring a user to interact with a maliciously crafted HTML page, requiring no privileges but user interaction such as visiting the page or granting permissions. Successful exploitation could lead to heap corruption, enabling high-impact consequences including unauthorized access to sensitive data, modification of system integrity, and disruption of availability.
Google's stable channel update for desktop, available at https://chromereleases.googleblog.com/2025/12/stable-channel-update-for-desktop_16.html, addresses the issue in Chrome 143.0.7499.147 and later versions. Additional details are provided in the Chromium issue tracker at https://issues.chromium.org/issues/448294721. Practitioners should prioritize updating affected Chrome installations to mitigate the risk.
