vulnerability analysis and mitigation

CVE-2021-37987 is a Use-after-free vulnerability discovered in the Network APIs of Google Chrome versions prior to 95.0.4638.54. The vulnerability was reported on May 8, 2021, and was officially patched in the Chrome stable channel update released on October 19, 2021. This security flaw affects Google Chrome browsers across Windows, Mac, and Linux operating systems (Chrome Release).

The vulnerability is classified as a Use-after-free (CWE-416) issue in Chrome's Network APIs. It received a CVSS v3.1 base score of 8.8 (HIGH), with a vector string of CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H. The vulnerability allows potential heap corruption exploitation through a specially crafted HTML page (NVD).

The vulnerability could allow a remote attacker to potentially exploit heap corruption, which could lead to arbitrary code execution, information disclosure, or denial of service. Given the high CVSS score and the critical nature of browser network APIs, successful exploitation could give attackers significant control over affected systems (NVD).

The vulnerability was patched in Chrome version 95.0.4638.54. Users and organizations are advised to update to this version or later. For Debian systems, the fix was included in version 97.0.4692.71-0.1~deb11u1 for the bullseye distribution (Debian Advisory).
