About this tag
PTP (Precision Time Protocol) discussions on WindowsForum.com focus on hardware timestamping and kernel-level fixes. A recent thread covers a Linux kernel patch (CVE-2025-38148) addressing a memory leak in the MSCC PHY PTP code related to one-step hardware timestamping. The leak could cause kernel memory exhaustion on systems using PTP, particularly in embedded appliances and telecom gear. The fix ensures timely release of timestamped frames. While not a remote code execution vulnerability, it is critical for resource management in PTP-enabled environments. The tag is relevant for users interested in time synchronization, kernel security, and hardware timestamping issues.

    Linux Kernel PTP One-Step Leak Fixed CVE-2025-38148

    A small, surgical change to the Linux kernel’s MSCC PHY PTP code closes a subtle but operationally important memory leak that could quietly consume kernel memory on systems that use one‑step hardware timestamping. The fix—recorded as CVE‑2025‑38148—ensures that frames for which the NIC hardware...
