Summary

In the Linux kernel, the DSA driver sja1105 rounds up the PTP perout pin duration to at least 1 tick to avoid division by zero in future_base_time().

Risk Assessment

Without the fix, division by zero could occur, potentially causing a system crash or incorrect PTP functionality.

Recommendation

Apply the Linux kernel update containing the fix for this CVE.

Original NVD description (English source)

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().
