Security News > 2021 > August > Google Patches Several Chrome Flaws That Can Be Exploited via Malicious Extensions
A Chrome 92 update released this week by Google patches 10 vulnerabilities, including several high-severity flaws that earned researchers tens of thousands of dollars in bug bounties.
Google described the issue as a heap buffer overflow in Bookmarks.
These were not the first extension-related Chrome vulnerabilities reported by Erceg to Google.
Another high-severity vulnerability for which Google paid out $20,000 is CVE-2021-30591, a use-after-free bug in the File System API. This issue was discovered by researcher SorryMybad from Kunlun Lab.
It's worth noting that Google pays out up to $20,000 for Chrome sandbox escape vulnerabilities described in a high-quality report.
Google this year patched more than half a dozen actively exploited zero-day flaws.
