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