Name of the Vulnerable Software and Affected Versions: Google Chrome versions prior to 85.0.4183.102

Description: The issue is related to a use after free in the offscreen canvas, which could allow a remote attacker to potentially exploit heap corruption via a crafted HTML page. This may enable the attacker to access confidential data, compromise data integrity, and cause a denial of service.

Recommendations: For versions prior to 85.0.4183.102, update to version 85.0.4183.102 or later to resolve the issue. As a temporary workaround, consider restricting access to potentially malicious HTML pages until the update is applied.
