The shift toward Rust components is intended to eliminate this class of defect long-term, but current C++ surfaces remain the dominant attack surface. Next release cadence and continued internal-only reporting suggest the volume of high-severity memory issues will stay elevated through Q4 2025.

⚡ Prediction

Google: At least four additional use-after-free CVEs will be fixed in Chrome 150 stable within 45 days of release.
