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-2025-40086 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-2025-40086/ (Markdown: https://insights.sbomify.com/CVE-2025-40086/index.md)","id":"CVE-2025-40086","markdown":"https://insights.sbomify.com/CVE-2025-40086/index.md","name":"CVE-2025-40086","record":{"aliases":["BELL-CVE-2025-40086","DEBIAN-CVE-2025-40086","GHSA-j8q5-7w54-24xj","ROOT-OS-DEBIAN-13-CVE-2025-40086","ROOT-OS-UBUNTU-2404-CVE-2025-40086","UBUNTU-CVE-2025-40086"],"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 local attacker can trigger a NULL pointer dereference in the Linux kernel's Xe GPU driver, causing 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/xe: Don't allow evicting of BOs in same VM in array of VM binds\n\nAn array of VM binds can potentially evict other buffer objects (BOs)\nwithin the same VM under certain conditions, which may lead to NULL\npointer dereferences later in the bind pipeline.
