Questions about CVE-2025-31200
What does this mean?
Processing an audio stream in a maliciously crafted media file can corrupt memory and lead to code execution on the device. Apple's fix adds improved bounds checking to the CoreAudio component.Source: support.apple.com
Am I affected, and how do I check?
Versions before iOS and iPadOS 18.4.1, macOS 15.4.1, tvOS 18.4.1, visionOS 2.4.1, and watchOS 11.5 are listed as affected. The exposure requires a device to process a crafted media file with an audio stream, and the listed iPhone and iPad models are the ones covered by the CoreAudio fix. To check a version, use Settings > General > About on iPhone, iPad, or Apple TV, or About This Mac on a Mac.Source: support.apple.com
What should I do about it?
Update to iOS 18.4.1, iPadOS 18.4.1, macOS 15.4.1, tvOS 18.4.1, visionOS 2.4.1, or watchOS 11.5, or a later release. No workaround is listed in the facts.Source: support.apple.com
Is it being exploited?
Yes. CISA added it to its Known Exploited Vulnerabilities catalog on 2025-04-17, which means it has evidence of attacks. No public exploit code is tracked.Source: cisa.gov, cve.now feed data
