Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to a warning that occurs when rm-raid devices are resumed after a table load because DM RECOVERY RUNNING is set. The failing check is designed to ensure that the sync thread isn't registered, but md check recovery can set MD RECOVERY RUNNING without the sync thread ever getting registered. Instead of checking if MD RECOVERY RUNNING is set, the fix involves checking if sync thread is non-NULL. The warning is triggered by the WARN ON ONCE function in the raid resume function.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
