The Apple macOS Security Update Review
We’ve received some feedback from those who read the Patch Blog that they would like something similar for macOS updates. Unfortunately, Apple doesn’t schedule these for a particular day, but we can provide our thoughts and analysis on the days they do release their latest patches.
For May 2026, Apple released 82 unique CVEs across the three macOS versions: 79 for macOS Tahoe 26. 5, 45 for macOS Sequoia 15. 7. 7, and 42 for macOS Sonoma 14. 8. 7. Since Apple doesn’t provide CVSS scores or other severity information, we’re left to speculate on which of these bugs is the most severe. However, there are a couple that stand out.
• CVE-2026-28819 (Wi-Fi) stands out as the strongest candidate for the most severe as it states, “An app may be able to execute arbitrary code with kernel privileges.”
