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-2025-40146 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-2025-40146/ (Markdown: https://insights.sbomify.com/CVE-2025-40146/index.md)","id":"CVE-2025-40146","markdown":"https://insights.sbomify.com/CVE-2025-40146/index.md","name":"CVE-2025-40146","record":{"aliases":["AZL-70004","BELL-CVE-2025-40146","DEBIAN-CVE-2025-40146","GHSA-mh62-fv56-v5jj","ROOT-OS-DEBIAN-11-CVE-2025-40146","ROOT-OS-DEBIAN-12-CVE-2025-40146","ROOT-OS-DEBIAN-13-CVE-2025-40146","ROOT-OS-UBUNTU-2204-CVE-2025-40146","ROOT-OS-UBUNTU-2404-CVE-2025-40146","UBUNTU-CVE-2025-40146"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"high_privilege","summary":"A local attacker with high privileges can trigger a deadlock in the Linux kernel block layer, causing a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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\nblk-mq: fix potential deadlock while nr_requests grown\n\nAllocate and free sched_tags while queue is freezed can deadlock[1],\nthis is a long term problem, hence allocate memory before freezing\nqueue and free memory after queue is unfreezed.\n\n[1] https://lore.kernel.org/all/0659ea8d-a463-47c8-9180-43c719e106eb@linux.ibm.com/","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":"blk-mq: fix potential deadlock while nr_requests grown","id":"CVE-2025-40146","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"blk-throttle: fix access race during throttle policy activation","id":"CVE-2025-40147"},"packages":[],"prev":{"headline":"PCI/pwrctrl: Fix double cleanup on devm_add_action_or_reset() failure","id":"CVE-2025-40145"},"products":["Linux"],"published":"2025-11-12","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":"2026-05-11","vendors":["Linux"]},"summary":"A local attacker with high privileges can trigger a deadlock in the Linux kernel block layer, causing a denial of service.","url":"https://insights.sbomify.com/CVE-2025-40146/"}
