CVE-2022-32917 Apple iOS, iPadOS, and macOS: memory-safety flaw

Confirmed exploited by CISA on · US federal patch deadline Oct 5, 2022
What to do
- Install Apple's security update for iOS, iPadOS, and macOS. If no update exists, follow the vendor's workaround or stop using the product until one ships.
- Install system updates the day they come out — most phone zero-days are fixed in a point release.
- Restart your phone every few days; some spyware does not survive a reboot.
- If you are a journalist, activist, lawyer, politician or executive, turn on Lockdown Mode (iPhone) or Advanced Protection (Android).
Who is affected
Could reach you. This one is aimed at devices or apps of the kind people own.
What's at risk: Messages, photos, location, microphone and camera. The most serious ones are "zero-click": no tap needed from the owner. They are usually used as spyware against a small number of chosen people.
