CVE-2026-72414
In the Linux kernel, the following vulnerability has been resolved:
net: dsa: sja1105: round up PTP perout pin duration
pin_duration is converted from the user-provided period to SJA1105
clock ticks and is later passed as the cycle_time argument to
future_base_time().
Very small period values may become zero after the conversion,
which can lead to a division by zero in future_base_time().
Round zero pin_duration up to 1 tick so that the smallest unsupported
periods use the minimum non-zero hardware duration instead of passing
zero to future_base_time().
