Description Preview
In the Linux kernel, specifically in the spi-hisi-kunpeng driver, a vulnerability has been identified where the max_speed_hz value provided by the firmware is not properly validated. If the value of max_speed_hz is set to 0, it can trigger a division by zero error in the hisi_calc_effective_speed() function. This vulnerability could potentially lead to system failure. To mitigate this issue, proper validation for the max_frequency value provided by the firmware has been added to prevent the occurrence of division by zero errors.
Overview
The vulnerability affects the Linux kernel's spi-hisi-kunpeng driver, potentially leading to a division by zero error if the max_speed_hz value is set to 0. The issue arises due to lack of verification for the max_frequency provided by the firmware.
Remediation
To remediate this vulnerability, users are advised to update their Linux kernel to versions that include the fix for the spi-hisi-kunpeng driver. The affected versions are:
- c770d8631e1810d8f1ce21b18ad5dd67eeb39e5c (less than 16ccaf581da4fcf1e4d66086cf37263f9a656d43)
- c770d8631e1810d8f1ce21b18ad5dd67eeb39e5c (less than ee73a15d4a8ce8fb02d7866f7cf78fcdd16f0fcc)
- c770d8631e1810d8f1ce21b18ad5dd67eeb39e5c (less than 5127c42c77de18651aa9e8e0a3ced190103b449c) Additionally, users should ensure that the max_speed_hz value provided by the firmware is properly validated to prevent division by zero errors.
