EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.7 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 76% 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).

Out-of-bounds Read (CWE-125) in BACnet packet parsing (bacdt_datetime_to_tod) in Loytec LIP-ME201C, L-INX, L-GATE, L-ROC, L-IOB, L-DALI, L-VIS and L-PAD through 8.4.18 on LINX-A64 allows an unauthenticated remote attacker to crash linx_a64.exe and ultimately reboot the device via a malformed BACnet TimeSynchronization or UTC-TimeSynchronization packet with an invalid month value. The same vulnerability affects multiple other Loytec products.
