A Use-after-free vulnerability (CVE-2024-6777) was discovered in the Navigation component of Google Chrome versions prior to 126.0.6478.182. The vulnerability was reported by Sven Dysthe (@svn-dys) on June 7, 2024, and was officially disclosed on July 16, 2024. This security flaw affects Google Chrome browsers and Chromium-based browsers like Microsoft Edge (Chrome Release, NVD).

The vulnerability is classified as a Use-after-free (CWE-416) issue in the Navigation component of Chrome. It received a CVSS v3.1 base score of 8.8 HIGH (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) from CISA-ADP, while NIST assigned it a score of 6.5 MEDIUM (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H). The vulnerability could potentially lead to heap corruption when exploited through a crafted Chrome Extension (NVD, Palo Alto).

If successfully exploited, this vulnerability allows an attacker who convinces a user to install a malicious extension to potentially exploit heap corruption via a crafted Chrome Extension. The high CVSS score indicates potential severe impacts on system confidentiality, integrity, and availability (NVD).
