High CVSS 8.7
CVE-2026-55732
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.
What this means
- Exposure
- Exploitable remotely over the network, without authentication and with no action from the victim.
- Impact
- An attacker can take the service offline.
- Weakness
- An out-of-bounds read exposes adjacent memory, often leftover secrets.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
