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-2022-49130 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-2022-49130/ (Markdown: https://insights.sbomify.com/CVE-2022-49130/index.md)","id":"CVE-2022-49130","markdown":"https://insights.sbomify.com/CVE-2022-49130/index.md","name":"CVE-2022-49130","record":{"aliases":["DEBIAN-CVE-2022-49130","GHSA-fjq8-jwg4-jxfg","UBUNTU-CVE-2022-49130"],"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 missing firmware file causes a null pointer dereference crash in the ath11k kernel driver during module removal, leading to denial of service.","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":"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-476","name":"NULL Pointer Dereference"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nath11k: mhi: use mhi_sync_power_up()\n\nIf amss.bin was missing ath11k would crash during 'rmmod ath11k_pci'. The\nreason for that was that we were using mhi_async_power_up() which does not\ncheck any errors. But mhi_sync_power_up() on the other hand does check for\nerrors so let's use that to fix the crash.\n\nI was not able to find a reason why an async version was used.\nath11k_mhi_start() (which enables state ATH11K_MHI_POWER_ON) is called from\nath11k_hif_power_up(), which can sleep.
