Name of the Vulnerable Software and Affected Versions Google Chrome versions prior to 80.0.3987.149

Description The issue is related to a use after free error in WebGL, which can be exploited by a remote attacker to potentially access confidential data, compromise data integrity, and cause a denial of service. This can be achieved via a crafted HTML page, allowing the attacker to exploit heap corruption.

Recommendations For versions prior to 80.0.3987.149, update to version 80.0.3987.149 or later to resolve the issue. As a temporary workaround, consider disabling WebGL until a patch is available. Restrict access to potentially malicious HTML pages to minimize the risk of exploitation.
