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-2026-80826 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-2026-80826/ (Markdown: https://insights.sbomify.com/CVE-2026-80826/index.md)","id":"CVE-2026-80826","markdown":"https://insights.sbomify.com/CVE-2026-80826/index.md","name":"CVE-2026-80826","record":{"aliases":["AZL-99611","BELL-CVE-2026-80826","DEBIAN-CVE-2026-80826","GHSA-24fg-x37m-25c7","UBUNTU-CVE-2026-80826"],"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 USB driver","requires_auth":"none","summary":"A use-after-free in the Linux kernel c67x00 USB driver allows local attackers to cause denial of service or execute arbitrary code.","user_interaction":"not_required","vuln_class":"use_after_free"},"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: c67x00: fix use-after-free in c67x00_add_iso_urb()\n\nWhen TD creation fails for the last packet of an isochronous URB,\nc67x00_add_iso_urb() gives the URB back before updating the endpoint\nscheduling state.\n\nc67x00_giveback_urb() frees the URB private data, and the completion\ncallback may release the final URB reference.
