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-2025-37794 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-2025-37794/ (Markdown: https://insights.sbomify.com/CVE-2025-37794/index.md)","id":"CVE-2025-37794","markdown":"https://insights.sbomify.com/CVE-2025-37794/index.md","name":"CVE-2025-37794","record":{"aliases":["BELL-CVE-2025-37794","DEBIAN-CVE-2025-37794","GHSA-mrf4-wfh4-qj5w","ROOT-OS-DEBIAN-12-CVE-2025-37794","ROOT-OS-UBUNTU-2204-CVE-2025-37794","ROOT-OS-UBUNTU-2404-CVE-2025-37794","UBUNTU-CVE-2025-37794"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel Wi-Fi","requires_auth":"low_privilege","summary":"A race condition in the Linux kernel Wi-Fi subsystem causes a null pointer dereference, leading to a system crash when stopping a virtual interface.","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":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mac80211: Purge vif txq in ieee80211_do_stop()\n\nAfter ieee80211_do_stop() SKB from vif's txq could still be processed.\nIndeed another concurrent vif schedule_and_wake_txq call could cause\nthose packets to be dequeued (see ieee80211_handle_wake_tx_queue())\nwithout checking the sdata current state.\n\nBecause vif.drv_priv is now cleared in this function, this could lead to\ndriver crash.\n\nFor example in ath12k, ahvif is store in vif.drv_priv.
