CVE-2025-32401
An Heap-based Buffer Overflow in RT-Labs P-Net version 1.0.1 or earlier allows an attacker to corrupt the memory of IO devices that use the library by sending a malicious RPC packet.
CVSS
- Version: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
- Base score: 9.8
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 0.33%
- Percentile among all scored CVEs: 24
- Score date: 10/5/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
