CVE-2025-71226

A compatibility issue was found in the Linux kernel's iwlwifi driver. The PTP clock registration for MVM/MLD interfaces lacks the required settime64 callback, causing a warning and PTP clock registration failure when the wireless interface starts. The fix adds a stub function returning -EOPNOTSUPP to satisfy the API requirement.

This is a driver compatibility issue rather than a security vulnerability. The missing callback causes a warning message and prevents PTP clock functionality from registering on Intel wireless adapters. There is no crash, data corruption, or exploitable behavior—the system continues to function normally without PTP support on the affected interface.
