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-2026-33554 in the wild and no public exploit code.\n\nAffected product: FreeIPMI. 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-2026-33554/ (Markdown: https://insights.sbomify.com/CVE-2026-33554/index.md)","id":"CVE-2026-33554","markdown":"https://insights.sbomify.com/CVE-2026-33554/index.md","name":"CVE-2026-33554","record":{"aliases":["ALSA-2026:13515","ALSA-2026:14819","ALSA-2026:19053","ALSA-2026:19208","ALSA-2026:20579","AZL-81423","BELL-CVE-2026-33554","CLSA-2026-1778617167","CLSA-2026-1778618041","DEBIAN-CVE-2026-33554","GHSA-382w-q5p9-3f2h","MGASA-2026-0078","OESA-2026-1737","OESA-2026-1738","OESA-2026-1739","OESA-2026-1740","OESA-2026-1741","OESA-2026-1801","RHSA-2026:13515","RHSA-2026:14819","RHSA-2026:19053","RHSA-2026:19208","RHSA-2026:20579","RLSA-2026:13515","RLSA-2026:14819","RLSA-2026:19053","RLSA-2026:19208","RLSA-2026:20579","SUSE-SU-2026:1754-1","SUSE-SU-2026:1755-1","SUSE-SU-2026:21212-1","SUSE-SU-2026:21231-1","SUSE-SU-2026:21446-1","SUSE-SU-2026:21680-1","openSUSE-SU-2026:10436-1","openSUSE-SU-2026:20556-1"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"IPMI management tool","requires_auth":"none","summary":"Buffer overflows in FreeIPMI ipmi-oem allow attackers to execute arbitrary code via crafted response messages from supported hardware.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"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-121","name":"Stack-based Buffer Overflow"}],"description":"ipmi-oem in FreeIPMI before 1.6.17 has exploitable buffer overflows on response messages. The Intelligent Platform Management Interface (IPMI) specification defines a set of interfaces for platform management. It is implemented by a large number of hardware manufacturers to support system management. It is most commonly used for sensor reading (e.g., CPU temperatures through the ipmi-sensors command within FreeIPMI) and remote power control (the ipmipower command). The ipmi-oem client command implements a set of a IPMI OEM commands for specific hardware vendors. If a user has supported hardware, they may wish to use the ipmi-oem command to send a request to a server to retrieve specific information. Three subcommands were found to have exploitable buffer overflows on response messages. They are: \"ipmi-oem dell get-last-post-code - get the last POST code and string describing the error on some Dell servers,\" \"ipmi-oem supermicro extra-firmware-info - get extra firmware info on Supermicro servers,\" and \"ipmi-oem wistron read-proprietary-string - read a proprietary string on Wistron servers.\"","ecosystems":["AlmaLinux:10","AlmaLinux:8","AlmaLinux:9","Red
