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-2022-21546 in the wild and no public exploit code.\n\nAffected product: Debian Debian 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-2022-21546/ (Markdown: https://insights.sbomify.com/CVE-2022-21546/index.md)","id":"CVE-2022-21546","markdown":"https://insights.sbomify.com/CVE-2022-21546/index.md","name":"CVE-2022-21546","record":{"aliases":["DEBIAN-CVE-2022-21546","GHSA-4f99-6w2j-877c","ROOT-OS-DEBIAN-11-CVE-2022-21546","ROOT-OS-UBUNTU-2204-CVE-2022-21546","UBUNTU-CVE-2022-21546"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel SCSI target","requires_auth":"none","summary":"A null pointer dereference in the Linux kernel SCSI target subsystem allows a local attacker to cause a system crash via crafted WRITE_SAME commands.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"oracle","cpe":[{"product":"debian_linux","vendor":"debian"},{"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-476","name":"NULL Pointer Dereference"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: target: Fix WRITE_SAME No Data Buffer crash\n\nIn newer version of the SBC specs, we have a NDOB bit that indicates there\nis no data buffer that gets written out.
