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-2026-80927 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-2026-80927/ (Markdown: https://insights.sbomify.com/CVE-2026-80927/index.md)","id":"CVE-2026-80927","markdown":"https://insights.sbomify.com/CVE-2026-80927/index.md","name":"CVE-2026-80927","record":{"aliases":["BELL-CVE-2026-80927","DEBIAN-CVE-2026-80927","GHSA-g365-rm76-m26c","UBUNTU-CVE-2026-80927"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A race condition in the Linux kernel timekeeping subsystem allows local attackers to leak uninitialized stack data to userspace.","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\ntimekeeping: Check the return value of tk_get_aux_ts64 in __do_adjtimex()\n\nIf the auxiliary clock is disabled during tk_get_aux_ts64() but is enabled\nbefore tks-\u003eclock_valid is checked, then uninitialized stackdata will be\nused in the calculations and indirectly leaked to userspace.\n\nThe same race window also exists after this change and also for the core\ntimekeeper.
