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-2026-74566 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2026-74566/ (Markdown: https://insights.sbomify.com/CVE-2026-74566/index.md)","id":"CVE-2026-74566","markdown":"https://insights.sbomify.com/CVE-2026-74566/index.md","name":"CVE-2026-74566","record":{"aliases":["AZL-96093","BELL-CVE-2026-74566","DEBIAN-CVE-2026-74566","GHSA-987h-mx48-c6mp","UBUNTU-CVE-2026-74566"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A local attacker can craft key descriptions to cause collisions in the Linux kernel keyring, leading to a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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\nkeys: make keyring key-chunk byte order agree with keyring_diff_objects()\n\nkeyring_get_key_chunk() loads description bytes into the index chunk low\naddress first, while keyring_diff_objects() numbers the first differing\nbit from the low end and folds the absolute byte index into the level\nwithout removing the inline-prefix offset the level already carries.\nThe two disagree on byte order and bit position, so the array can be\ntold two keys first differ at a bit that does not differ in the chunk\nthe walker uses, letting crafted descriptions collide into one node.\n\nLoad the chunk in the order keyring_diff_objects() assumes and drop the\ninline-prefix length when folding the byte index into the level.
