Name of the Vulnerable Software and Affected Versions Linux Kernel (affected versions not specified)

Description A race condition exists within the SCSI layer of the Linux kernel that can prevent the error handler from being woken up, leading to stuck I/O operations. This occurs due to memory ordering issues in scsi dec host busy() and scsi eh inc host failed(). Specifically, the write operation clearing SCMD STATE INFLIGHT can be reordered with reads counting in scsi host busy(), potentially causing other CPUs to observe an incorrect busy count. Additionally, counting busy commands before incrementing host failed can race with a final command in scsi dec host busy(), preventing the error handler task from being woken up.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
