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-2023-54071 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-2023-54071/ (Markdown: https://insights.sbomify.com/CVE-2023-54071/index.md)","id":"CVE-2023-54071","markdown":"https://insights.sbomify.com/CVE-2023-54071/index.md","name":"CVE-2023-54071","record":{"aliases":["BELL-CVE-2023-54071","DEBIAN-CVE-2023-54071","GHSA-66p3-rgg9-52hr","ROOT-OS-UBUNTU-2204-CVE-2023-54071","UBUNTU-CVE-2023-54071"],"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 bug in the rtw88 WiFi driver causes a kernel warning and potential instability during rate updates, leading to denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/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 work to update rate to avoid RCU warning\n\nThe ieee80211_ops::sta_rc_update must be atomic, because\nieee80211_chan_bw_change() holds rcu_read lock while calling\ndrv_sta_rc_update(), so create a work to do original things.\n\n Voluntary context switch within RCU read-side critical section!\n WARNING: CPU: 0 PID: 4621 at kernel/rcu/tree_plugin.h:318\n rcu_note_context_switch+0x571/0x5d0\n CPU: 0 PID: 4621 Comm: kworker/u16:2 Tainted: G        W  OE\n Workqueue: phy3 ieee80211_chswitch_work [mac80211]\n RIP: 0010:rcu_note_context_switch+0x571/0x5d0\n Call Trace:\n  \u003cTASK\u003e\n  __schedule+0xb0/0x1460\n  ? __mod_timer+0x116/0x360\n  schedule+0x5a/0xc0\n  schedule_timeout+0x87/0x150\n  ? trace_raw_output_tick_stop+0x60/0x60\n  wait_for_completion_timeout+0x7b/0x140\n  usb_start_wait_urb+0x82/0x160 [usbcore\n  usb_control_msg+0xe3/0x140 [usbcore\n  rtw_usb_read+0x88/0xe0 [rtw_usb\n  rtw_usb_read8+0xf/0x10 [rtw_usb\n  rtw_fw_send_h2c_command+0xa0/0x170 [rtw_core\n  rtw_fw_send_ra_info+0xc9/0xf0 [rtw_core\n  drv_sta_rc_update+0x7c/0x160 [mac80211\n  ieee80211_chan_bw_change+0xfb/0x110 [mac80211\n  ieee80211_change_chanctx+0x38/0x130 [mac80211\n  ieee80211_vif_use_reserved_switch+0x34e/0x900 [mac80211\n  ieee80211_link_use_reserved_context+0x88/0xe0 [mac80211\n  ieee80211_chswitch_work+0x95/0x170 [mac80211\n  process_one_work+0x201/0x410\n  worker_thread+0x4a/0x3b0\n  ? process_one_work+0x410/0x410\n  kthread+0xe1/0x110\n  ? kthread_complete_and_exit+0x20/0x20\n  ret_from_fork+0x1f/0x30\n  \u003c/TASK\u003e","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: rtw88: use work to update rate to avoid RCU warning","id":"CVE-2023-54071","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":3,"next":{"headline":"ALSA: pcm: Fix potential data race at PCM memory allocation helpers","id":"CVE-2023-54072"},"packages":[],"prev":{"headline":"igb: clean up in all error paths when enabling SR-IOV","id":"CVE-2023-54070"},"products":["Linux"],"published":"2025-12-24","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-15","vendors":["Linux"]},"summary":"A bug in the rtw88 WiFi driver causes a kernel warning and potential instability during rate updates, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2023-54071/"}
