CVE-2026-111731: Infinite loop when reading PDPortDataCheck record of subslot 0
- Severity: high (CVSS 8.7 v4.0)
- Exploited in the wild: not listed in CISA KEV
- EPSS: 0.4% probability of exploitation in the next 30 days
- Public exploit or detection template: none known
- Published: 2026-10-29 · updated 2026-10-29
- Weakness: CWE-835
Description
P-Net before 1.0.3 enters an infinite loop when handling a read request for the PDPortDataCheck record with subslot 0 (whole module). The loop over the ports never advanced to the next port, so the request never completes and the device stops responding. A remote unauthenticated attacker can use this to cause a denial of service.
Affected products
- RT-Labs P-Net: before 1.0.3 — fixed in 1.0.3
How to fix
Upgrade to a fixed version: RT-Labs P-Net 1.0.3. Check the vendor advisory for mitigations.
