Apple has released another IOS 15 update with patches for 22 serious security defects in a wide range of iPhone and iPad software components.
The vulnerabilities are serious enough to expose iPhone and iPad users to malicious hacker attacks via rigged PDF or image files.
In an advisory documenting the vulnerabilities, Apple said the iOS 15.1 and iPadOS 15.1 updates provide cover for 22 flaws (counting by CVEs), some serious enough to cause arbitrary code execution or privilege escalation attacks.
Apple said iOS 15 software components vulnerable to code execution attacks include ColorSync (CVE-2021-30917), CoreGraphics (CVE-2021-30919), FileProvider (CVE-2021-30881), GPU Drivers, Image Processing, and a trio of kernel flaws.

The company also patched privilege escalation issues in iCloud and information disclosure issues in Siri and Model I/O.
The iOS 15.1 update is available for iPhone 6s and later, iPad Pro (all models), iPad Air 2 and later, iPad 5th generation and later, iPad mini 4 and later, and iPod touch (7th generation)
This new patch comes just a few weeks after Apple rushed out an urgent iOS 15 patch to address a software flaw being “actively exploited” in the wild.
The latest point-update follows the release of iOS 15 with a built-in two-factor authentication code generator and multiple anti-tracking security and privacy features.
