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-2026-74402/ (Markdown: https://insights.sbomify.com/CVE-2026-74402/index.md)","id":"CVE-2026-74402","markdown":"https://insights.sbomify.com/CVE-2026-74402/index.md","name":"CVE-2026-74402","record":{"aliases":["BELL-CVE-2026-74402","DEBIAN-CVE-2026-74402","GHSA-5f8p-9776-4575","UBUNTU-CVE-2026-74402"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["other"],"network_reachable":"unknown","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A flaw in the Atmel SHA204A kernel driver caused weak entropy generation, potentially compromising cryptographic security for users relying on this hardware random number generator.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"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\ncrypto: atmel-sha204a - fix blocking and non-blocking rng logic\n\nThe blocking and non-blocking paths were failing to provide valid entropy\ndue to improper buffer management.
