Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A deadlock in the error handler of the Linux kernel's scsi: ufs component has been resolved. The deadlock occurs when all tags are allocated and the SCSI error handler calls
ufshcd eh host reset handler(), which queues work that calls ufshcd err handler(). This results in a lockup. The issue is fixed by making ufshcd exec dev cmd() allocate a reserved request.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
