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-2026-98778 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-2026-98778/ (Markdown: https://insights.sbomify.com/CVE-2026-98778/index.md)","id":"CVE-2026-98778","markdown":"https://insights.sbomify.com/CVE-2026-98778/index.md","name":"CVE-2026-98778","record":{"aliases":["AZL-109454","BELL-CVE-2026-98778","DEBIAN-CVE-2026-98778","GHSA-v997-cq9r-p9v8","UBUNTU-CVE-2026-98778"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A local attacker can trigger a logic error in the Linux kernel binder driver to close unrelated file descriptors, potentially causing denial of service or information disclosure.","user_interaction":"not_required","vuln_class":"other"},"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the Linux kernel, the following vulnerability has been resolved:\n\nbinder: fix is_failure flag for superseded transaction cleanup\n\nWhen a TF_UPDATE_TXN transaction supersedes a pending async transaction,\nbinder_release_entire_buffer() is called with is_failure=false.
