Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to the iommu/iova component of the Linux kernel, where there is a problem with the
retry pfn overflowing in the alloc and insert iova range function. This occurs in two situations: when the first iova size exceeds the domain size, and when the node with the largest iova->pfn lo value in the iova domain is deleted. As a result, if the retry logic is executed, low pfn is updated to 0, and then new pfn < low pfn returns false to make the allocation successful.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
