Linux Kernel Vulnerability Affecting iavf Implementation

CVE-2025-68752

What is CVE-2025-68752?

A vulnerability exists within the Linux kernel's iavf component concerning the ptp_clock_settime() functionality. This issue arises due to the assumption that every ptp_clock supports the settime64() method. To mitigate risks associated with potential NULL dereferences, a safeguard has been implemented to return -EOPNOTSUPP where necessary. This prevention mechanism enhances the stability and security of systems utilizing the Linux kernel.
