Name of the Vulnerable Software and Affected Versions Google Chrome versions prior to 91.0.4472.77

Description The issue is related to an out of bounds memory access in the WebAudio component of Google Chrome, which can be exploited by a remote attacker using a crafted HTML page. This can potentially allow the attacker to access confidential data, compromise data integrity, and cause a denial of service. The estimated number of potentially affected devices worldwide is not specified.
