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-2025-40033 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-2025-40033/ (Markdown: https://insights.sbomify.com/CVE-2025-40033/index.md)","id":"CVE-2025-40033","markdown":"https://insights.sbomify.com/CVE-2025-40033/index.md","name":"CVE-2025-40033","record":{"aliases":["BELL-CVE-2025-40033","DEBIAN-CVE-2025-40033","GHSA-7wxp-97wr-wj5g","ROOT-OS-DEBIAN-13-CVE-2025-40033","ROOT-OS-UBUNTU-2404-CVE-2025-40033","UBUNTU-CVE-2025-40033"],"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":"high_privilege","summary":"A local attacker with high privileges can cause a denial of service in the Linux kernel via a NULL pointer dereference in the PRU remoteproc driver.","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\nremoteproc: pru: Fix potential NULL pointer dereference in pru_rproc_set_ctable()\n\npru_rproc_set_ctable() accessed rproc-\u003epriv before the IS_ERR_OR_NULL\ncheck, which could lead to a null pointer dereference.
