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-2026-97590/ (Markdown: https://insights.sbomify.com/CVE-2026-97590/index.md)","id":"CVE-2026-97590","markdown":"https://insights.sbomify.com/CVE-2026-97590/index.md","name":"CVE-2026-97590","record":{"aliases":["BELL-CVE-2026-97590","DEBIAN-CVE-2026-97590","GHSA-9wm4-m683-cr29","UBUNTU-CVE-2026-97590"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read"],"network_reachable":"unknown","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"An attacker with local access could potentially read sensitive cryptographic data from unscrubbed temporary buffers in the s390 PAES implementation.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ns390/crypto: Fix missing scrub of temp buffers with PAES algorithm\n\nIn function ctr_paes_do_crypt() there is a buffer used to process\nremaining bytes \u003c AES_BLOCK_SIZE.
