Detailsinfo

A vulnerability classified as critical was found in Linux Kernel up to 6.6.50/6.10.9. Affected by this vulnerability is the function hisi_calc_effective_speed of the component hisi-kunpeng. The manipulation with an unknown input leads to a divide by zero vulnerability. The CWE definition for the vulnerability is CWE-369. The product divides a value by zero. As an impact it is known to affect availability. The summary by CVE is:

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 advisory is shared at git.kernel.org. This vulnerability is known as CVE-2024-47664 since 09/30/2024. Technical details are known, but no exploit is available.

The vulnerability scanner Nessus provides a plugin with the ID 210933 (openSUSE 15 Security Update : kernel (SUSE-SU-2024:3983-1)), which helps to determine the existence of the flaw in a target environment.
