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-2026-82946/ (Markdown: https://insights.sbomify.com/CVE-2026-82946/index.md)","id":"CVE-2026-82946","markdown":"https://insights.sbomify.com/CVE-2026-82946/index.md","name":"CVE-2026-82946","record":{"aliases":["GHSA-m2qv-7w8c-3r6g"],"analysis":null,"analysis_generated_by":null,"assigner":"ENISA","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-690","name":"Unchecked Return Value to NULL Pointer Dereference"},{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"SOEM version 2.0.0 and earlier contains a vulnerability where a malicious device can crash the master system. When the software receives an error response, it clears an internal pointer but continues processing. If another message arrives before timeout, the software attempts to use the cleared pointer, causing a crash.
