CVE-2026-40279

BACnet Stack is a BACnet open source protocol stack C library for embedded systems. Prior to 1.4.3, decodesigned32 in src/bacnet/bacint.c reconstructs a 32-bit signed integer from four APDU bytes using signed left shifts. When any of the four bytes has bit 7 set value ≥ 0x80, the left-shift...
