The latest Chrome security update started rolling out on Monday with patches for 11 vulnerabilities.

Ten of the addressed vulnerabilities were reported by external researchers. Of these, eight are rated “high severity” and two “medium severity.”

Six of the externally reported security holes are use-after-free bugs, which in some cases can lead to code execution. Five of them have a severity rating of “high.”

The remaining issues that were reported by external researchers include inappropriate implementations, insufficient policy enforcement, and a type confusion in the V8 engine, Google notes in its advisory.

Google has paid a total of $13,000 in bug bounty rewards to the reporting researchers, but it has yet to determine the amounts to be paid for more than half of these security defects.

The highest payout – $6,000 – went to an anonymous researcher for a use-after-free in a storage component.

The internet giant also awarded Sven Dysthe and Irvan Kurniawan with $3,000 each for two inappropriate implementation issues in compositing and full screen, and handed out $1,000 to Samet Bekmezci for a use-after-free bug in BFCache.

The latest browser iteration is currently rolling out to Windows, Mac, and Linux users as Chrome 100.0.4896.88.

Chrome 100 was released in the stable channel less than two weeks ago, shortly after Google issued an emergency fix to address a zero-day vulnerability.
