ptp timestamp

About this tag
The ptp timestamp tag on WindowsForum.com covers discussions about Precision Time Protocol (PTP) timestamping, particularly in the context of Linux kernel drivers and network hardware. A notable thread addresses CVE-2024-42107, a TOCTOU race condition in the Intel ice Ethernet driver where an external timestamp interrupt handler could process a PTP timestamp after the driver released its clock, leading to a NULL-pointer dereference and kernel panic. The tag is relevant for users interested in PTP timestamping, kernel security vulnerabilities, and network driver stability.

  1. CVE-2024-42107 TOCTOU in Intel ice Driver Fixed Upstream (Kernel Panic)

    The Linux kernel patch for CVE-2024-42107 fixes a race in the Intel "ice" network driver where an external timestamp interrupt handler could process a timestamp after the driver had released its Precision Time Protocol (PTP) clock — a timing-of-check/time-of-use (TOCTOU) race that could produce...
