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-2025-40131 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-2025-40131/ (Markdown: https://insights.sbomify.com/CVE-2025-40131/index.md)","id":"CVE-2025-40131","markdown":"https://insights.sbomify.com/CVE-2025-40131/index.md","name":"CVE-2025-40131","record":{"aliases":["BELL-CVE-2025-40131","DEBIAN-CVE-2025-40131","GHSA-m4rx-9548-xc7v","UBUNTU-CVE-2025-40131"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel WiFi driver","requires_auth":"none","summary":"A null pointer dereference in the ath12k WiFi driver during monitor mode can cause a kernel warning and potential denial of service.","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\nwifi: ath12k: Fix peer lookup in ath12k_dp_mon_rx_deliver_msdu()\n\nIn ath12k_dp_mon_rx_deliver_msdu(), peer lookup fails because\nrxcb-\u003epeer_id is not updated with a valid value.
