Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A vulnerability has been resolved in the Linux kernel related to the handling of suspended arrays in the
md check recovery() function. The issue arises when the mddev suspend() function does not stop the sync thread, causing problems when trying to unregister the sync thread. This can lead to a hang when stopping the array after it has been suspended. The problem is not limited to dm-raid and can be fixed by ignoring suspended arrays in md check recovery(). Follow-up patches will improve dm-raid to better handle frozen sync threads during suspension.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
