Last modified
CVE-2026-55732 is a high-severity vulnerability rated 8.7/10 on the CVSS scale. 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.. EPSS estimates a 0.32% chance of exploitation in the next 30 days.
