Google Discovers Attack Exploiting Chrome Zero-Day Vulnerability

Google on Monday announced the release of 11 security patches for Chrome, including one for a vulnerability exploited in the wild.

Google on Monday announced the release of 11 security patches for Chrome, including one for a vulnerability exploited in the wild.

Tracked as CVE-2022-0609 and rated high severity, the exploited vulnerability is described as a use-after-free issue in Animation that was reported by Adam Weidemann and Clément Lecigne of Google’s Threat Analysis Group.

“Google is aware of reports that an exploit for CVE-2022-0609 exists in the wild,” the Internet giant notes in an advisory.

While the company did not provide additional information on the exploited zero-day, use-after-free bugs are typically exploited to achieve the execution of arbitrary code on vulnerable systems.

This is the first exploited Chrome zero-day patched by Google in 2022. According to data from the company’s Project Zero group, there were 14 exploited Chrome flaws last year.

Rolling out to Windows, Mac and Linux systems as Chrome 98.0.4758.102, the new browser iteration addresses six other high-severity and one medium-severity security flaws reported by external researchers.

The most important of these is CVE-2022-0603, a use-after-free in file manager. Google paid the reporting researcher a $15,000 bug bounty reward.

Next in line are CVE-2022-0604 (heap buffer overflow in tab groups), CVE-2022-0605 (use-after-free in Webstore API), and CVE-2022-0606 (use-after-free in Angle). The company handed out $7,000 bounty payouts for each of these.

The remaining high-severity flaws addressed with this Chrome release are CVE-2022-0607 (use-after-free in GPU) and CVE-2022-0608 (integer overflow in Mojo). Tracked as CVE-2022-0610, the medium-severity security hole is described as an inappropriate implementation issue in the Gamepad API.

According to Google, Chrome users will receive the new update in the coming days/weeks. Those who do not want to wait can trigger the update immediately by going to Menu > Help > About Google Chrome.
