CVE-2026-72156

CVE-2026-72156 : In the Linux kernel, the vulnerability affects the fpga: microchip-spi path in mpf_ops_parse_header(), where header_size is read from the bitstream at MPF_HEADER_SIZE_OFFSET (24). If header_size is zero, the code evaluates *(buf + header_size - 1), which dereferences before the b...
