Apple has rolled out security updates to address dozens of iOS and macOS vulnerabilities, including a severe iOS bug dubbed WiFiDemon that could lead to denial of service or arbitrary code execution.

The vulnerability, tracked as CVE-2021-30800 and a zero-day bug when security researcher Carl Schou publicly disclosed it, was fixed by Apple with the release of iOS 14.7 earlier this week.
