Google has patched 27 vulnerabilities with the release of Chrome 104 on Tuesday, and the researchers who reported some of these security holes earned thousands of dollars in bug bounties.
The internet giant has paid out a total of approximately $90,000 for the flaws patched in the latest version of Chrome, but it has yet to determine the rewards for two of the issues, including a high-severity bug.
The highest bug bounty, $15,000, was earned by an anonymous researcher who discovered a use-after-free vulnerability in the Omnibox component.
Use-after-free vulnerabilities are commonly found in Chrome. These types of flaws can often be exploited to escape the browser’s sandbox, but they are in many cases only useful to attackers when combined with other flaws.
Researchers Nan Wang and Guang Gong of 360 Alpha Lab earned $10,000 for a use-after-free in the Safe Browsing component. The white hat hackers have also been awarded an additional $7,000 for two other vulnerabilities.
Others received between $1,000 and $7,000 for their findings.
None of the vulnerabilities appears to have been exploited in attacks. Google has learned about four actively exploited Chrome flaws this year, including CVE-2022-2294, which has been linked to an Israeli spyware company and used in targeted attacks aimed at entities in the Middle East.
