Google Patches 27 Security Flaws in Chrome 150 Update

Google has released Chrome 150.0.7871.114/115 for Windows and macOS, and Chrome 150.0.7871.114 for Linux, addressing 27 security vulnerabilities, including two rated as critical. The update follows an earlier Chrome 150 release issued just one day prior, which also contained security fixes but without detailed disclosures.

According to Google, none of the newly patched vulnerabilities are known to be actively exploited.

Two Critical Vulnerabilities Fixed

In the Chrome Releases blog, Google detailed the 27 vulnerabilities resolved in the latest update.

The two most severe issues are:

• CVE-2026-15112 — Use-after-free (UAF) vulnerability in Ozone
• CVE-2026-15129 — Use-after-free (UAF) vulnerability in Views

Use-after-free vulnerabilities can allow attackers to execute arbitrary code by exploiting improper memory handling, making them among the most serious browser security issues.

In total, the update fixes:

• 2 critical vulnerabilities
• 23 high-severity vulnerabilities
• 2 medium-severity vulnerabilities

Memory safety bugs continue to dominate Chrome’s security fixes, with 13 of the 27 vulnerabilities falling into the use-after-free category.

Most Bugs Discovered Internally

Google reports that it internally discovered 24 of the 27 vulnerabilities, while external security researchers identified the remaining three.

The company awarded $3,000 in bug bounty rewards for the externally reported issues.

Follows Chrome 150 Major Release

The latest security patch arrives shortly after Google’s major Chrome 150 release, which addressed more than 400 security vulnerabilities, including numerous critical flaws.

This smaller follow-up update focuses on additional security issues identified after the major release.

Google has also released:
