  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: dsa: sja1105: round up PTP perout pin duration\n\npin_duration is converted from the user-provided period to SJA1105\nclock ticks and is later passed as the cycle_time argument to\nfuture_base_time().\n\nVery small period values may become zero after the conversion,\nwhich can lead to a division by zero in future_base_time().\n\nRound zero pin_duration up to 1 tick so that the smallest unsupported\nperiods use the minimum non-zero hardware duration instead of passing\nzero to future_base_time().",
