AI risk analysis

Summary: This flaw in the Linux kernel's AMD KFD driver allows an attacker to cause memory leaks or crashes by failing page migration from device to system RAM, potentially leading to resource exhaustion or system instability.
Exploitability: Exploitation requires IOMMU enabled and specific conditions for page migration failure. It is moderately difficult to exploit.
Blast radius: If exploited, the impact could range from resource exhaustion to system crashes, affecting the stability and performance of the system.
Detection: No reliable host or network indicator is derivable from the published description.
Prioritized remediation: Upgrade to the Linux kernel version 6.1.13 or later.

NVD description

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Fix error path at svm_migrate_copy_to_ram If page migration from device to sys ram fails for some reasons driver needs release and unlock allocated system pages. To do that driver should use page physical address, or pfn, then get struct page*. Current driver uses dma address(for adev) that is not correct with IOMMU enabled, or even in general. The patch releases and unlocks allocated system pages based on where migration failed by struct page* of sys ram pages. Also dma_unmap correspodent system ram pages at error path.
