Google on Wednesday announced a Chrome 150 security update that resolves 27 vulnerabilities, including two critical-severity flaws.

The two critical bugs are use-after-free issues in Chrome’s Ozone and Views components. Both were found by Google last month.

The Chrome refresh resolves a total of 13 use-after-free defects, including 10 high-severity and one medium-severity weakness.

Other types of vulnerabilities patched in this update include uninitialized use, integer overflow, out-of-bounds read and write, insufficient validation of untrusted input, inappropriate implementation, insufficient data validation, and insufficient policy enforcement.

Most of these flaws were discovered by Google, a trend that has been ongoing for over two months. Per Google’s advisory, only three of the newly resolved security defects were reported by external researchers, who received a total of $3,000 in bug bounty rewards.
