AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions Google Chrome versions prior to 88.0.4324.146

Description The issue is related to a heap buffer overflow in the Tab Groups component of Google Chrome. This could allow an attacker, who has convinced a user to install a malicious extension, to potentially exploit heap corruption via a crafted Chrome Extension. The exploitation of this issue may impact the confidentiality, integrity, and availability of protected information.

Recommendations For versions prior to 88.0.4324.146, update to version 88.0.4324.146 or later to resolve the issue. As a temporary workaround, consider disabling the use of Tab Groups until a patch is available. Restrict the installation of extensions to only trusted sources to minimize the risk of exploitation.
