An off-by-one read/write issue was found in the SDHCI device of QEMU. It occurs when reading/writing the Buffer Data Port Register in sdhci_read_dataport and sdhci_write_dataport respectively if data_count == block_size. A malicious guest could use this flaw to crash the QEMU process on the host resulting in a denial of service condition.
