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-2025-39991 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-2025-39991/ (Markdown: https://insights.sbomify.com/CVE-2025-39991/index.md)","id":"CVE-2025-39991","markdown":"https://insights.sbomify.com/CVE-2025-39991/index.md","name":"CVE-2025-39991","record":{"aliases":["BELL-CVE-2025-39991","DEBIAN-CVE-2025-39991","GHSA-2v74-9vqm-pm8p","ROOT-OS-UBUNTU-2404-CVE-2025-39991","UBUNTU-CVE-2025-39991"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel WiFi driver","requires_auth":"none","summary":"A NULL pointer dereference in the ath11k WiFi driver can cause a kernel crash, leading to denial of service for local attackers.","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: ath11k: fix NULL dereference in ath11k_qmi_m3_load()\n\nIf ab-\u003efw.m3_data points to data, then fw pointer remains null.\nFurther, if m3_mem is not allocated, then fw is dereferenced to be\npassed to ath11k_err function.\n\nReplace fw-\u003esize by m3_len.\n\nFound by Linux Verification Center (linuxtesting.org) with SVACE.","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":"wifi: ath11k: fix NULL dereference in ath11k_qmi_m3_load()","id":"CVE-2025-39991","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2025"},"n_packages":0,"n_references":5,"next":{"headline":"mm: swap: check for stable address space before operating on the VMA","id":"CVE-2025-39992"},"packages":[],"prev":{"headline":"bpf: Check the helper function is valid in get_helper_proto","id":"CVE-2025-39990"},"products":["Linux"],"published":"2025-10-15","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":"2026-09-14","vendors":["Linux"]},"summary":"A NULL pointer dereference in the ath11k WiFi driver can cause a kernel crash, leading to denial of service for local attackers.","url":"https://insights.sbomify.com/CVE-2025-39991/"}
