A buffer overflow vulnerability exists in the mstp.ko kernel module, responsible for processing BACnet MS/TP frames over serial (RS485). The SendFrame() function writes directly into a statically sized kernel buffer (alloc_entry(0x1f5)) without validating the length of attacker-controlled data (param_5). If an MS/TP frame contains a crafted payload exceeding 492 bytes, the function performs out-of-bounds writes beyond the allocated 501-byte buffer, corrupting kernel memory. This flaw allows local or physically connected attackers to trigger denial-of-service or achieve remote code execution in kernel space. Tested against version 3.08.03 with a custom BACnet frame over /dev/ttyS0.
