CVE-2024-50178

CVSS v3.1

5.5

Medium

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified)
Description: The issue concerns the use of smp processor id() in preemptible code, which can lead to errors when the driver is enabled. The problem arises from the loongson3 cpufreq probe() function calling do service request(), where smp processor id() is used. This can cause bugs, as indicated by the error message "using smp processor id() in preemptible [00000000] code." The solution involves using raw smp processor id() instead of smp processor id() in do service request() to prevent these errors.
Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
