CVE-2025-24265: An out-of-bounds read was addressed with improved bounds checking.
An out-of-bounds read was addressed with improved bounds checking. This issue is fixed in macOS Sequoia 15.4, macOS Sonoma 14.7.5, macOS Ventura 13.7.5. An app may be able to cause unexpected system termination.
Security readout for executives and security teams
Plain-English summary
CVE-2025-24265 is an Apple macOS memory-safety flaw that can let an app trigger unexpected system termination. For executives, the main business concern is service disruption on affected Macs. Apple says the issue is fixed in macOS Sequoia 15.4, Sonoma 14.7.5, and Ventura 13.7.5.
Executive priority
Prioritize normal emergency patch handling for affected Macs, especially where downtime would disrupt business operations. Current sources support a serious availability risk, but not confirmed active exploitation.
Technical view
The issue is an out-of-bounds read, mapped to CWE-125, addressed by Apple with improved bounds checking. The provided CVSS 3.1 score is 9.8, but Apple’s stated impact is limited to an app causing unexpected system termination. No affected subsystem is identified in the provided sources.
Likely exposure
Organizations with managed or unmanaged Macs running macOS Sequoia before 15.4, Sonoma before 14.7.5, or Ventura before 13.7.5 should treat those systems as exposed.
Exploitation context
The source bundle does not show CISA KEV listing or any cited evidence of active exploitation. Apple’s description requires an app to trigger the condition, but the sources do not provide exploit details, prerequisites, or observed attacks.
Researcher notes
Evidence is limited to Apple’s advisory text and CVE metadata. The CVSS vector indicates broad severity, while Apple’s published impact states unexpected system termination. Do not infer code execution, data theft, or active exploitation from the provided sources.
Mitigation direction
Update macOS Sequoia systems to 15.4 or later.
Update macOS Sonoma systems to 14.7.5 or later.
Update macOS Ventura systems to 13.7.5 or later.
Use Apple security guidance for systems outside those update paths.
Prioritize Macs supporting critical operations or privileged users.
Validation and detection
Inventory macOS versions across managed and unmanaged endpoints.
Confirm affected Macs meet Apple’s fixed version thresholds.
Verify CVE-2025-24265 appears in the relevant Apple security content.
Review MDM or patch-management reporting for successful update completion.
Track exceptions for Macs that cannot receive the fixed releases.

Out-of-bounds Read
Out-of-bounds Read represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
