Detailsinfo

A vulnerability classified as problematic has been found in Linux Kernel up to 6.18.39/7.1.4. Affected is the function __device_links_no_driver of the file drivers/base/core.c of the component hisi_sas. The manipulation with an unknown input leads to a race condition vulnerability. CWE is classifying the issue as CWE-362. The product contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently. This is going to have an impact on integrity, and availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: scsi: hisi_sas: Add slave_destroy interface for v3 hw WARNING is triggered when executing link reset of remote PHY and rmmod SAS driver simultaneously.
