AI Analysis
Technical Summary
This vulnerability (CVE-2026-43744) is an out-of-bounds write (CWE-787) in the audio stream processing component of Apple iOS and iPadOS. When a specially crafted media file is processed, it may trigger a write outside the intended memory bounds, leading to process termination (denial of service). Apple fixed this issue by improving bounds checking in iOS 26.6 and iPadOS 26.6, as well as in several macOS, tvOS, visionOS, and watchOS versions. The CVSS v3.1 base score is 5.5 (medium severity), reflecting local attack vector, low complexity, no privileges required, user interaction required, unchanged scope, and impact limited to availability.
Potential Impact
Successful exploitation results in denial of service by terminating the affected process handling the audio stream. There is no impact on confidentiality or integrity. The vulnerability requires local access and user interaction to trigger the process termination.
Mitigation Recommendations
A fix is available in iOS 26.6 and iPadOS 26.6. Users and administrators should update affected devices to these versions or later to remediate the vulnerability. No additional mitigation steps are indicated by the vendor advisory.
