CVE-2026-72156 in Linux
요약
\~에 의해 MITRE • 2026. 08. 15.
In the Linux kernel, the following vulnerability has been resolved:
fpga: microchip-spi: fix zero header_size OOB read in mpf_ops_parse_header()
mpf_ops_parse_header() reads header_size from the bitstream at MPF_HEADER_SIZE_OFFSET (24). When header_size is zero, the expression *(buf + header_size - 1) reads one byte before the buffer start.
Since initial_header_size is set to 71 in mpf_ops, the fpga-mgr core guarantees the buffer is large enough to reach MPF_HEADER_SIZE_OFFSET. The only real gap is the zero header_size case, which cannot be resolved by providing a larger buffer, so return -EINVAL.
