Google this week announced the release of Chrome 97 in the stable channel with a total of 37 security fixes, including 24 for vulnerabilities reported by external researchers.
Of the 24 externally reported security flaws, one is rated critical severity, 10 high severity, 10 medium, and three low. The most common types of vulnerabilities are use-after-free (seven bugs), and improper implementation (eight issues).
The most severe is CVE-2022-0096, a use-after-free issue in Storage that could be exploited to execute code in the context of the browser.
Five of the 10 high-severity flaws addressed with this Chrome release are use-after-free errors affecting components such as screen capture, sign-in, SwiftShader, PDF, and Autofill.
The other five are an inappropriate implementation in DevTools, type confusion in V8, and heap buffer overflows in Bookmarks, V8, and ANGLE.
Half of the medium-severity issues are improper implementation bugs, affecting components such as navigation, Autofill, Blink, and compositing.
The remaining flaws include a use-after-free in File Manager API, incorrect security UI in Autofill and Browser UI, out-of-bounds memory access in Web Serial, and uninitialized-use in File API.
The low-severity errors fixed in this Chrome release include a policy bypass in Service Workers and inappropriate implementations in WebShare and passwords.
Google made no mention in its advisory of any of the addressed vulnerabilities being exploited in malicious attacks.
To date, the Internet search giant has paid a total of $54,000 in bug bounty rewards to the reporting researchers. However, the company has yet to share details on over half of the bounty payouts.
The latest browser release is now rolling out to Windows, Mac, and Linux machines as Chrome 97.0.4692.71.
