After releasing iOS 16.4.1 last Friday to fix a series of bugs and patch two critical security flaws, Apple has released iOS 15.7.5 and iPadOS 15.7.5 to address the same security issues in pre-iPhone 8 models. The update doesn’t appear to offer any additional enhancements and is recommended for all users.
According to Apple’s security content page, the two fixes are the same as the ones patched in iOS 16.4.1 and iPadOS 16.4.1 last week. It is only for the following devices: iPhone 6s (all models), iPhone 7 (all models), iPhone SE (1st generation), iPad Air 2, iPad mini (4th generation), and iPod touch (7th generation).

Apple says the vulnerabilities may have already been actively exploited, and the speed at which they pushed out the update suggests it’s extremely serious. Apple generally releases security update for older iPhones alongside larger iOS updates.
