Impact and Mitigation

The most severe of these vulnerabilities, CVE-2024-6990, involves an uninitialized use in Dawn, a graphics abstraction layer. This flaw could potentially allow attackers to execute arbitrary code on affected systems.

The other two vulnerabilities, CVE-2024-7255 and CVE-2024-7256, involve out-of-bounds reads in WebTransport and insufficient data validation in Dawn. If left unpatched, both could lead to similar exploitation scenarios.

Google has restricted access to detailed information about these bugs until most users have updated their browsers. This precaution prevents malicious actors from exploiting the vulnerabilities before users can protect themselves.

Google expressed gratitude to the security researchers who contributed to identifying these vulnerabilities. The company emphasized the importance of collaboration with the security community to enhance the safety and reliability of its products.

Users are encouraged to update their browsers promptly and report any new issues through the bug filing system or the community help forum.
