Kernel code execution via SMB buffer overflow
Published Mar 31, 2025 · Updated Apr 2, 2026
Buffer overflow in Apple macOS SMB allows local users to execute arbitrary code with kernel privileges through a malicious app. The SMB component mishandles memory and overflows a buffer, but Apple has not published the affected routine or triggering input. Exploitation requires a local app and user interaction, and successful exploitation grants kernel-level code execution.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <13.7.5
- Affected versionversion=0 <14.7.5
- Affected versionversion=0 <15.4
