The issue allows a remote attacker to potentially exploit heap corruption via a crafted web app, due to a use after free in the Network component. The severity of this issue is classified as Medium by Chromium.

The issue is related to the use of memory after it has been freed, which can be exploited by an attacker to potentially cause a denial of service. This can be achieved by convincing a user to install a specially crafted extension, allowing the attacker to exploit heap corruption. The estimated number of potentially affected devices and details about real-world incidents are not provided.
