9.6

Critical

Base vector

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

Name of the Vulnerable Software and Affected Versions Google Chrome versions prior to 87.0.4280.141

Description The issue is related to the use of memory after it has been freed, which could allow a remote attacker who has compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. This could impact the confidentiality, integrity, and availability of protected information.

Recommendations For versions prior to 87.0.4280.141, update to version 87.0.4280.141 or later to resolve the issue. As a temporary workaround, consider restricting access to potentially vulnerable media components in Google Chrome until a patch is applied.
