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-2026-98830 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-2026-98830/ (Markdown: https://insights.sbomify.com/CVE-2026-98830/index.md)","id":"CVE-2026-98830","markdown":"https://insights.sbomify.com/CVE-2026-98830/index.md","name":"CVE-2026-98830","record":{"aliases":["AZL-108972","BELL-CVE-2026-98830","DEBIAN-CVE-2026-98830","GHSA-m222-4jcj-v2hx","UBUNTU-CVE-2026-98830"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel WiFi driver","requires_auth":"none","summary":"A buffer overflow in the Linux kernel wfx WiFi driver allows attackers to execute code or cause denial of service via malicious firmware responses.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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\nwifi: wfx: validate MIB read length before copying to caller\n\nwfx_hif_read_mib() copies reply-\u003elength bytes from the firmware\nresponse into the caller-provided buffer without checking that\nreply-\u003elength does not exceed val_len.
