Security readout for executives and security teams
Plain-English summary
CVE-2025-24139 is an Apple macOS file-parsing issue. If a user opens a maliciously crafted file, an app may unexpectedly terminate. Apple addressed it with improved checks in listed macOS security updates. The provided sources do not show active exploitation.
Executive priority
Prioritize routine-to-urgent patching for macOS fleets, particularly user workstations exposed to external files. The issue requires user interaction, but Apple rates the impact high through CVSS metrics.
Technical view
Apple describes this as CWE-787, fixed with improved checks. CVSS 3.1 is 7.8: local attack vector, low complexity, no privileges, user interaction required, and high CIA impact. Public detail is limited to malicious file parsing causing unexpected app termination.
Likely exposure
Organizations with Macs running affected macOS releases before Apple’s listed fixes may be exposed, especially where users handle external, emailed, downloaded, or shared files. The affected product is macOS; the sources do not identify a narrower component.
Exploitation context
Exploitation requires user interaction with a maliciously crafted file on a vulnerable Mac. No CISA KEV listing is present in the provided data, and the cited sources do not claim active exploitation.
Researcher notes
Public technical information is sparse. The CVE identifies CWE-787 and file parsing, but not the exact parser, file format, crash condition, or exploitability beyond Apple’s summary. Avoid assuming code execution or active exploitation without additional sourced evidence.
Mitigation direction
- Update macOS to Sequoia 15.3, Sonoma 14.7.3, or Ventura 13.7.3/13.7.5 as applicable.
- Review Apple advisories for the correct update path for each managed Mac.
- Use MDM to enforce macOS security update compliance.
- Reduce exposure to untrusted file attachments and downloads until systems are updated.
Validation and detection
- Inventory macOS versions across managed and unmanaged Macs.
- Confirm systems meet or exceed Apple’s fixed versions listed for this CVE.
- Check MDM or endpoint telemetry for update installation success.
- Review Apple support pages for any later guidance or superseding updates.
