CVE-2026-72414

/// Technical 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().

/// Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
