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-2026-93146 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-2026-93146/ (Markdown: https://insights.sbomify.com/CVE-2026-93146/index.md)","id":"CVE-2026-93146","markdown":"https://insights.sbomify.com/CVE-2026-93146/index.md","name":"CVE-2026-93146","record":{"aliases":["AZL-102281","BELL-CVE-2026-93146","DEBIAN-CVE-2026-93146","GHSA-477f-qmj2-58hm","UBUNTU-CVE-2026-93146"],"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 missing validation in the Linux kernel time namespace allows local attackers to cause incorrect calculations or unexpected behavior via invalid nanosecond values.","user_interaction":"not_required","vuln_class":"integer_overflow"},"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\ntime/namespace: Validate nanosecond field in proc_timens_set_offset()\n\nThe function validates tv_sec to be within [-KTIME_SEC_MAX, KTIME_SEC_MAX]\nbut never validates that tv_nsec is within the valid range of\n[0, NSEC_PER_SEC-1] before using it in timespec64_add().\n\ntimespec64_add() expects both timespec64 structures to have normalized\nvalues with tv_nsec in the range [0, 999999999].
