Chrome 147, Firefox 150 Security Updates Rolling Out

The browser refreshes resolve critical and high-severity vulnerabilities that could lead to arbitrary code execution.

Google and Mozilla on Tuesday announced fresh security updates for Chrome and Firefox users, addressing multiple memory safety vulnerabilities.

The new Chrome 147 update is rolling out with 30 security fixes, including four for critical-severity use-after-free flaws reported by external researchers.

Tracked as CVE-2026-7363, CVE-2026-7361, CVE-2026-7344, and CVE-2026-7343, the bugs impact the Canvas, iOS, Accessibility, and Views browser components.

Use-after-free issues are a type of memory safety defects that occur when an application continues to point to memory that has been deallocated, and could lead to arbitrary code execution, information disclosure, or crashes.

Nearly all of the remaining 26 flaws addressed in Chrome this week are memory safety bugs, including 16 high-severity use-after-free issues. High-severity out-of-bounds, buffer overflow, and type confusion bugs were also addressed.
