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-2024-56609 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-2024-56609/ (Markdown: https://insights.sbomify.com/CVE-2024-56609/index.md)","id":"CVE-2024-56609","markdown":"https://insights.sbomify.com/CVE-2024-56609/index.md","name":"CVE-2024-56609","record":{"aliases":["BELL-CVE-2024-56609","DEBIAN-CVE-2024-56609","GHSA-74p7-5m3q-64m6","ROOT-OS-DEBIAN-11-CVE-2024-56609","ROOT-OS-DEBIAN-12-CVE-2024-56609","ROOT-OS-UBUNTU-2204-CVE-2024-56609","UBUNTU-CVE-2024-56609"],"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":"low_privilege","summary":"A race condition in the rtw88 WiFi driver during module removal can cause a kernel warning and potential system instability.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: rtw88: use ieee80211_purge_tx_queue() to purge TX skb\n\nWhen removing kernel modules by:\n   rmmod rtw88_8723cs rtw88_8703b rtw88_8723x rtw88_sdio rtw88_core\n\nDriver uses skb_queue_purge() to purge TX skb, but not report tx status\ncausing \"Have pending ack frames!\" warning.
