It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-57999 in the wild and no public exploit code.\n\nAffected product: Linux kernel. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2024-57999/ (Markdown: https://insights.sbomify.com/CVE-2024-57999/index.md)","id":"CVE-2024-57999","markdown":"https://insights.sbomify.com/CVE-2024-57999/index.md","name":"CVE-2024-57999","record":{"aliases":["BELL-CVE-2024-57999","DEBIAN-CVE-2024-57999","GHSA-2qw8-jh79-6qc9","ROOT-OS-DEBIAN-12-CVE-2024-57999","ROOT-OS-UBUNTU-2204-CVE-2024-57999","ROOT-OS-UBUNTU-2404-CVE-2024-57999","UBUNTU-CVE-2024-57999"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A flaw in the Linux kernel's PowerPC IOMMU driver causes a kernel OOPS during boot when MMIO ranges intersect with Dynamic DMA Windows.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\npowerpc/pseries/iommu: IOMMU incorrectly marks MMIO range in DDW\n\nPower Hypervisor can possibily allocate MMIO window intersecting with\nDynamic DMA Window (DDW) range, which is over 32-bit addressing.\n\nThese MMIO pages needs to be marked as reserved so that IOMMU doesn't map\nDMA buffers in this range.\n\nThe current code is not marking these pages correctly which is resulting\nin LPAR to OOPS while booting.
