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.
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.
Se encontró un problema de lectura/escritura de uno en uno en el dispositivo SDHCI de QEMU. Ocurre al leer/escribir el registro del Puerto de Datos del Búfer en sdhci_read_dataport y sdhci_write_dataport, respectivamente, si data_count == block_size. Un invitado malintencionado podría utilizar esta falla para bloquear el proceso QEMU en el host, lo que resultaría en una condición de denegación de servicio.
