Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
An issue exists in the md/bitmap component where the
backlog store() function suspends the array before verifying the existence of a write-mostly device. If no such device is found, the error path only unlocks the reconfig mutex, leaving the array in a suspended state, which blocks subsequent I/O operations.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
