Apple has released the iPadOS 17.7.8 update on Monday, following the recent but short-lived iPadOS 17.7.7 version. The earlier update was quickly pulled due to multiple user complaints, including problems with Touch ID login and apps resetting to their initial screens. This new update aims to fix critical security vulnerabilities and stability issues that surfaced in previous versions, ensuring a smoother and safer user experience for compatible iPad devices.
The iPadOS 17.7.8 update carries the build number 21H440 and is available for select models, including the iPad Pro 12.9-inch (2017), iPad Pro 10.5-inch, and the 2018 iPad. Apple specifically mentions that this update replaces the problematic 17.7.7 firmware. Users who experienced disruptions such as apps failing to launch properly or authentication issues with Touch ID should find those problems resolved with this release.
Among the key security fixes, Apple patched a vulnerability in AirDrop that allowed apps to access arbitrary file metadata without permission, now restricted by enhanced permission controls. Additionally, the update addresses a “double free” flaw in the Audio component that could cause unexpected system crashes. Other critical fixes include improved entitlement checks in iCloud Document Sharing to prevent unauthorized folder sharing, as well as tightened lock screen authentication to block unauthorized access to Notes.
Apple also tackled several kernel-level security issues in this update. The previous kernel flaws could have led to memory corruption, unauthorized access to sensitive kernel information, and app crashes. With iPadOS 17.7.8, Apple has removed vulnerable code sections, improved memory handling, and reinforced overall system stability. This update highlights Apple’s ongoing commitment to protecting user data and maintaining device reliability through timely security patches.
