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-2022-50554 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-2022-50554/ (Markdown: https://insights.sbomify.com/CVE-2022-50554/index.md)","id":"CVE-2022-50554","markdown":"https://insights.sbomify.com/CVE-2022-50554/index.md","name":"CVE-2022-50554","record":{"aliases":["AZL-76767","DEBIAN-CVE-2022-50554","GHSA-rmfg-487h-3qfx","ROOT-OS-DEBIAN-11-CVE-2022-50554","ROOT-OS-UBUNTU-2204-CVE-2022-50554","UBUNTU-CVE-2022-50554"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel block layer","requires_auth":"low_privilege","summary":"A race condition in the Linux kernel block layer can cause a double queue request, leading to a kernel panic 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":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nblk-mq: avoid double -\u003equeue_rq() because of early timeout\n\nDavid Jeffery found one double -\u003equeue_rq() issue, so far it can\nbe triggered in VM use case because of long vmexit latency or preempt\nlatency of vCPU pthread or long page fault in vCPU pthread, then block\nIO req could be timed out before queuing the request to hardware but after\ncalling blk_mq_start_request() during -\u003equeue_rq(), then timeout handler\nmay handle it by requeue, then double -\u003equeue_rq() is caused, and kernel\npanic.\n\nSo far, it is driver's responsibility to cover the race between timeout\nand completion, so it seems supposed to be solved in driver in theory,\ngiven driver has enough knowledge.\n\nBut it is really one common problem, lots of driver could have similar\nissue, and could be hard to fix all affected drivers, even it isn't easy\nfor driver to handle the race.
