How CVE-2025-24230 Works

This vulnerability stems from improper bounds checking when parsing malicious audio files. Attackers craft audio files with malformed metadata or oversized buffers, triggering an out-of-bounds read when processed by affected Apple operating systems. The flaw resides in the audio decoding component, where insufficient validation allows memory corruption, leading to app crashes (denial of service) or potential arbitrary code execution. The CVSS 4.0 score reflects critical severity due to the possibility of remote exploitation via crafted media.

DailyCVE Form

Platform: Apple OS stack
Version: visionOS <2.4, macOS What Undercode Say:

Exploitation:

1. Craft a malicious audio file (e.g., .m4a, .aac) with oversized metadata chunks.
2. Use social engineering to distribute via Messages, Mail, or web downloads.

3. Trigger parsing via default media handlers.

PoC Code (Python Audio Header Manipulation):

with open("exploit.m4a", "wb") as f:
f.write(b"ftypmp42" + b"\xff" 1024) Corrupted header

Detection:

Check installed Apple OS versions:
sw_vers macOS
system_profiler SPSoftwareDataType Detailed report

Mitigation:

1. Patch immediately via `Software Update` or Apple’s security advisories.
2. Disable automatic preview of audio files in Mail/Safari:

   defaults write com.apple.mail DisableInlineAttachmentViewing -bool YES
   

3. Network controls: Block suspicious audio MIME types (audio/) at firewalls.

Post-Exploit Forensics:

Check crash logs for audio-related failures:
log show --predicate 'process == "mediaserverd"' --last 24h

Apple’s Official Patch Notes:

Fixed: Audio file parsing memory corruption (CVE-2025-24230).
