CVE-2021-47480

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

Description The issue is related to the SCSI host release mechanism in the Linux kernel. When a SCSI device is freed, the SCSI host release is triggered, and it is essential to ensure that the low-level device driver module is not unloaded before the SCSI host instance is released. This is because the shost->hostt is required in the release handler. The problem can lead to a kernel panic with the message 'BUG: unable to handle page fault for address'. The issue was reported by Changhui and Yi.

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