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-2026-98860 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-2026-98860/ (Markdown: https://insights.sbomify.com/CVE-2026-98860/index.md)","id":"CVE-2026-98860","markdown":"https://insights.sbomify.com/CVE-2026-98860/index.md","name":"CVE-2026-98860","record":{"aliases":["BELL-CVE-2026-98860","DEBIAN-CVE-2026-98860","GHSA-243p-r44x-jh77","UBUNTU-CVE-2026-98860"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read","other"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel HID","requires_auth":"none","summary":"A type confusion in the Linux kernel HID BPF subsystem allows hardware errors to be misinterpreted as success, potentially exposing uninitialized memory to BPF programs.","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\nHID: bpf: cast size to ssize_t when checking hid_bpf_hw_request\n\nAs reported by Sashiko:\nIf a transport driver encounters a hardware error and returns a negative\nerror code such as -EPIPE, ret is implicitly promoted to size_t when\ncompared against size.
