CVE-2026-71263

The FreeModbus LINUXTCP port has a concrete defect in xMBPortTCPPool(): the code uses a strict greater-than check (usTCPFrameBytesLeft > MB_TCP_BUF_SIZE) against a 263-byte MB_TCP_BUF_SIZE limit. When an MBAP frame with Length 264 is processed, usTCPFrameBytesLeft becomes 263, the check passes...

CVE-2026-71261 dr_wav.h W64 CUE Chunk Metadata Parsing Integer Overflow Leading to Heap Buffer Overflow on 32-bit Builds

drlibs drwav.h all versions through current master contains an integer overflow in W64 CUE chunk metadata parsing. In drwavmetadataprocesschunk, a stage-1 capacity estimate truncates the 64-bit W64 chunk sizeInBytes to sizet before dividing by DRWAVCUEPOINTBYTES; on 32-bit builds this truncation...
