Deeper analysis

CVE-2025-8292 is a use-after-free vulnerability (CWE-416) in the Media Stream component of Google Chrome prior to version 138.0.7204.183. Published on 2025-07-30, it enables a remote attacker 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).

The vulnerability can be exploited by a remote attacker with no privileges over the network and low attack complexity, though it requires user interaction such as visiting a malicious site. Successful exploitation could achieve high impacts on confidentiality, integrity, and availability, potentially allowing heap corruption that leads to arbitrary code execution.

Google's stable channel update for Chrome desktop, announced at https://chromereleases.googleblog.com/2025/07/stable-channel-update-for-desktop_29.html, patches the issue in version 138.0.7204.183. Further details are available in the Chromium issue tracker at https://issues.chromium.org/issues/426054987. Mitigation involves updating affected Chrome installations to 138.0.7204.183 or later.
