DescriptionCVE.org

An out-of-bounds write issue was addressed by removing the vulnerable code. This issue is fixed in iOS 26.6 and iPadOS 26.6, macOS Sequoia 15.7.8, macOS Sonoma 14.8.8, macOS Tahoe 26.6, tvOS 26.6, visionOS 26.6, watchOS 26.6. Processing a maliciously crafted file may lead to unexpected app termination or arbitrary code execution.

AnalysisAI

Arbitrary code execution in Apple iOS and iPadOS, macOS, tvOS, visionOS, and watchOS permits an attacker to run code or terminate apps by luring a user into opening a crafted file. The out-of-bounds write issue was fixed in all supported Apple operating systems via June 2026 updates. No active exploitation or public proof-of-concept has been reported at time of analysis, and EPSS indicates a low probability of future exploitation.
