What to do

AI-suggested

A fix has been implemented in the Linux kernel to validate the max_speed_hz value and reject zero values. Users should update to the fixed kernel version containing this validation. No additional mitigation is required beyond applying the official fix.

Description

A vulnerability in the Linux kernel's hisi-kunpeng SPI driver was addressed by adding verification for the max_frequency value provided by firmware. If the max_speed_hz value is zero, it could cause a division by zero error in the hisi_calc_effective_speed() function, potentially leading to system failure. The fix treats zero as invalid and returns an error code to prevent this issue.
