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 76.0.3809.87

Description The issue is related to a use after free in WebAudio, which can lead to heap corruption. A remote attacker can potentially exploit this via a crafted HTML page, allowing for arbitrary code execution. The vulnerability is caused by an out-of-bounds operation in the offline audio context component of the web browser.

Recommendations For versions prior to 76.0.3809.87, update to version 76.0.3809.87 or later to resolve the issue. As a temporary workaround, consider restricting access to WebAudio components until the update is applied. Avoid using the offline audio context feature in Google Chrome until the issue is resolved.
