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-2026-23322 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-2026-23322/ (Markdown: https://insights.sbomify.com/CVE-2026-23322/index.md)","id":"CVE-2026-23322","markdown":"https://insights.sbomify.com/CVE-2026-23322/index.md","name":"CVE-2026-23322","record":{"aliases":["BELL-CVE-2026-23322","DEBIAN-CVE-2026-23322","GHSA-668m-q5h4-jfjc","UBUNTU-CVE-2026-23322"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel IPMI","requires_auth":"low_privilege","summary":"A use-after-free vulnerability in the Linux kernel IPMI driver allows attackers to cause memory corruption, potentially leading to code execution or system crashes.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nipmi: Fix use-after-free and list corruption on sender error\n\nThe analysis from Breno:\n\nWhen the SMI sender returns an error, smi_work() delivers an error\nresponse but then jumps back to restart without cleaning up properly:\n\n1. intf-\u003ecurr_msg is not cleared, so no new message is pulled\n2. newmsg still points to the message, causing sender() to be called\n   again with the same message\n3.
