An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-64003 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-2026-64003/ (Markdown: https://insights.sbomify.com/CVE-2026-64003/index.md)","id":"CVE-2026-64003","markdown":"https://insights.sbomify.com/CVE-2026-64003/index.md","name":"CVE-2026-64003","record":{"aliases":["BELL-CVE-2026-64003","DEBIAN-CVE-2026-64003","GHSA-rqvx-8pr4-6wfh","UBUNTU-CVE-2026-64003"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A flaw in the Linux kernel SCSI core causes device removal hangs during recovery, leading to denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-772","name":"Missing Release of Resource after Effective Lifetime"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: core: Run queues for all non-SDEV_DEL devices from scsi_run_host_queues\n\nWhile a SCSI host is in a recovery state, scsi_mq_requeue_cmd() will not\nset the requeue list for a requeued command to be kicked in the future.\nThe expectation is a call to scsi_run_host_queues() will kick all SCSI\ndevices once the recovery state is cleared.\n\nHowever, scsi_run_host_queues() uses shost_for_each_device() which uses\nscsi_device_get() and so will ignore devices in a partially removed\nstate like SDEV_CANCEL.
