EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 5.9 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.1%, top 99% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Nozomi Networks Labs identified a CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') vulnerability in the event notification functionality of KUNBUS piControl in version 2.6.2 that allows a local authenticated attacker to corrupt kernel heap and event-list state and disclose a small amount of adjacent kernel memory, resulting in kernel memory corruption and denial of service, by issuing concurrent crafted requests from multiple threads through the piControl character device.
