Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A NULL pointer dereference exists in the IOMMU subsystem. The
group->domain pointer can be NULL if a default domain fails to allocate during the first probe. This leads to a system crash when the pci dev reset iommu done() function invokes iommu attach device(), which then attempts to dereference domain->ops->attach dev.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
