Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> spi: hisi-kunpeng: Add verification for the max_frequency provided by the firmware<br /> <br /> If the value of max_speed_hz is 0, it may cause a division by zero<br /> error in hisi_calc_effective_speed().<br /> The value of max_speed_hz is provided by firmware.<br /> Firmware is generally considered as a trusted domain. However, as<br /> division by zero errors can cause system failure, for defense measure,<br /> the value of max_speed is validated here. So 0 is regarded as invalid<br /> and an error code is returned.
