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-2022-49123 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-2022-49123/ (Markdown: https://insights.sbomify.com/CVE-2022-49123/index.md)","id":"CVE-2022-49123","markdown":"https://insights.sbomify.com/CVE-2022-49123/index.md","name":"CVE-2022-49123","record":{"aliases":["GHSA-26p5-hwvm-hf8m","ROOT-OS-DEBIAN-11-CVE-2022-49123","ROOT-OS-UBUNTU-2204-CVE-2022-49123","UBUNTU-CVE-2022-49123"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A deadlock in the ath11k Wi-Fi driver causes management frame flush failures, leading to system hangs and denial of service.","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":5.5,"severity":"medium","source":"cisa-adp","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-667","name":"Improper Locking"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nath11k: Fix frames flush failure caused by deadlock\n\nWe are seeing below warnings:\n\nkernel: [25393.301506] ath11k_pci 0000:01:00.0: failed to flush mgmt transmit queue 0\nkernel: [25398.421509] ath11k_pci 0000:01:00.0: failed to flush mgmt transmit queue 0\nkernel: [25398.421831] ath11k_pci 0000:01:00.0: dropping mgmt frame for vdev 0, is_started 0\n\nthis means ath11k fails to flush mgmt. frames because wmi_mgmt_tx_work\nhas no chance to run in 5 seconds.\n\nBy setting /proc/sys/kernel/hung_task_timeout_secs to 20 and increasing\nATH11K_FLUSH_TIMEOUT to 50 we get below warnings:\n\nkernel: [  120.763160] INFO: task wpa_supplicant:924 blocked for more than 20 seconds.\nkernel: [  120.763169]       Not tainted 5.10.90 #12\nkernel: [  120.763177] \"echo 0 \u003e /proc/sys/kernel/hung_task_timeout_secs\" disables this message.\nkernel: [  120.763186] task:wpa_supplicant  state:D stack:    0 pid:  924 ppid:     1 flags:0x000043a0\nkernel: [  120.763201] Call Trace:\nkernel: [  120.763214]  __schedule+0x785/0x12fa\nkernel: [  120.763224]  ?
