CVE-2026-43659 is a race condition vulnerability in Apple FileProvider that affects multiple Apple operating systems, including iOS, iPadOS, macOS, and visionOS. The flaw allows an application to access sensitive user data due to improper handling of concurrent operations. Apple indicates the issue was addressed by adding additional validation, which is consistent with a timing-dependent access control or state validation weakness in FileProvider. The vulnerability is documented as affecting iOS 18.7.9 and earlier, iPadOS 18.7.9 and earlier, iOS 26.5 and iPadOS 26.5 and earlier, macOS Sequoia 15.7.7 and earlier, macOS Sonoma 14.8.7 and earlier, macOS Tahoe 26.5 and earlier, and visionOS 26.5 and earlier.
