CVE-2024-50195 is an input-validation vulnerability in the Linux kernel's pc_clock_settime() function. The function fails to validate the timespec64 timestamp before passing it to Precision Time Protocol (PTP) clock-setting operations through ptp->info->settime64(). Invalid inputs include negative seconds, nanoseconds outside 0–999,999,999, and timestamps outside the permitted time range. Some PTP drivers, including hclge_ptp_settime(), igb_ptp_settime_i210(), and _rcar_gen4_ptp_settime(), use these fields directly to program hardware registers, relying on validation by higher layers. The fix adds timespec64_valid_strict() validation and rejects invalid timestamps with -EINVAL.
