Base vector

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 89.0.4389.114

Description: The issue is related to a use after free in Aura, which can lead to a buffer overflow in memory. This can potentially allow a remote attacker to execute arbitrary code or cause a denial of service by exploiting heap corruption via a crafted HTML page.

Recommendations: For versions prior to 89.0.4389.114, update to version 89.0.4389.114 or later to resolve the issue. As a temporary workaround, consider restricting access to potentially malicious HTML pages to minimize the risk of exploitation.
