| Subject: CVE-2024-47664: spi: hisi-kunpeng: Add verification for the max_frequency provided by the firmware |
| |
| Description |
| =========== |
| |
| 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. |
| |
| The Linux kernel CVE team has assigned CVE-2024-47664 to this issue. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
| https://git.kernel.org/stable/c/16ccaf581da4fcf1e4d66086cf37263f9a656d43 |
