CVE-2026-72414

net: dsa: sja1105: round up PTP perout pin duration

State: Published
Severity: Not scored
Published: Aug 15, 2026
Updated: Aug 17, 2026
Reserved: Aug 9, 2026

Description

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().

Scores

The record has no CVSS score.
