It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-98759 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-2026-98759/ (Markdown: https://insights.sbomify.com/CVE-2026-98759/index.md)","id":"CVE-2026-98759","markdown":"https://insights.sbomify.com/CVE-2026-98759/index.md","name":"CVE-2026-98759","record":{"aliases":["BELL-CVE-2026-98759","DEBIAN-CVE-2026-98759","GHSA-34hh-4678-7488","UBUNTU-CVE-2026-98759"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel USB driver","requires_auth":"none","summary":"An attacker with physical access can trigger uninitialized memory usage in the Linux kernel USB Type-C driver, potentially leaking stack data or executing arbitrary code.","user_interaction":"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\nusb: typec: tipd: fix uninitialized typec_partner_desc in cd321x_update_work()\n\ncd321x_update_work() passes a stack-allocated typec_partner_desc to\ntypec_register_partner() after initializing only usb_pd, accessory and\nidentity.\n\ntypec_register_partner() copies attach and deattach from the descriptor\ninto the partner.
