# Security digest: December 13, 2022

1 editorial brief.

## Take stock

- Check exposure: Operation Triangulation . Owners of iPhones or iPads below iOS 16.3 (on 16) or 15.7.8 (on 15), Macs below Ventura 13.2, Monterey 12.6.8 or Big Sur 11.7.9, and Apple Watches or TVs below watchOS 9.3 or tvOS 16.3.
- None of it touches your stack? Then there is nothing to do today. That is a result, not a failure to read carefully.

## Editorial briefs

- **Check exposure** [Apple Triangulation Font Bug and Kernel PAC Bypass in KEV](https://erroneo.us/security/briefs/apple-ios-triangulation-font-cve-2023-41990-pac-cve-2022-48618/index.md): Both bugs were fixed in late 2022 and early 2023 and only matter for Apple devices that never updated past those builds, but they were real spyware tools, so find any device still that old.

## Known exploited (CISA KEV)

None.

## Critical advisories

None.
