To do that driver should use page\nphysical address, or pfn, then get struct page*. Current driver uses dma\naddress(for adev) that is not correct with IOMMU enabled, or even in general.\n\nThe patch releases and unlocks allocated system pages based on where migration\nfailed by struct page* of sys ram pages. Also dma_unmap correspodent system\nram pages at error path.","cvssScore":7.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/960c4a8069bfd352c48cc88592618f1ebe24c69e","tags":[]},{"url":"https://git.kernel.org/stable/c/a2035918a7a1d8fd3bb79d22e1e149294a5a8418","tags":[]},{"url":"https://git.kernel.org/stable/c/da87bcad1f781d822e7ced6d1de9dbc6d381c72e","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":{"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.
