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-2025-40339 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2025-40339/ (Markdown: https://insights.sbomify.com/CVE-2025-40339/index.md)","id":"CVE-2025-40339","markdown":"https://insights.sbomify.com/CVE-2025-40339/index.md","name":"CVE-2025-40339","record":{"aliases":["AZL-71801","BELL-CVE-2025-40339","DEBIAN-CVE-2025-40339","GHSA-jq6r-3qg9-jgcw","ROOT-OS-DEBIAN-11-CVE-2025-40339","ROOT-OS-DEBIAN-12-CVE-2025-40339","ROOT-OS-DEBIAN-13-CVE-2025-40339","ROOT-OS-UBUNTU-2204-CVE-2025-40339","ROOT-OS-UBUNTU-2404-CVE-2025-40339","UBUNTU-CVE-2025-40339"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A null pointer dereference in the AMD GPU driver allows local attackers to cause a system crash.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amdgpu: fix nullptr err of vm_handle_moved\n\nIf a amdgpu_bo_va is fpriv-\u003eprt_va, the bo of this one is always NULL.\nSo, such kind of amdgpu_bo_va should be updated separately before\namdgpu_vm_handle_moved.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"drm/amdgpu: fix nullptr err of vm_handle_moved","id":"CVE-2025-40339","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2025"},"n_packages":0,"n_references":3,"next":{"headline":"drm/xe: Fix oops in xe_gem_fault when running core_hotunplug test.","id":"CVE-2025-40340"},"packages":[],"prev":{"headline":"ASoC: Intel: avs: Do not share the name pointer between components","id":"CVE-2025-40338"},"products":["Linux"],"published":"2025-12-09","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A null pointer dereference in the AMD GPU driver allows local attackers to cause a system crash.","url":"https://insights.sbomify.com/CVE-2025-40339/"}
