CVE-2026-35170 Details
Description
openFPGALoader is a utility for programming FPGAs. In 1.1.1 and earlier, a heap-buffer-overflow read vulnerability exists in BitParser::parseHeader() that allows out-of-bounds heap memory access when parsing a crafted .bit file. No FPGA hardware is required to trigger this vulnerability.
A heap buffer overflow vulnerability has been identified in openFPGALoader versions through 3429d34. The issue arises in the BitParser::parseHeader() function, where the absence of proper bounds checking allows for out-of-bounds access to heap memory when parsing a specially crafted .bit file. This vulnerability does not require any FPGA hardware to be exploited.
