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-2026-80797 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-2026-80797/ (Markdown: https://insights.sbomify.com/CVE-2026-80797/index.md)","id":"CVE-2026-80797","markdown":"https://insights.sbomify.com/CVE-2026-80797/index.md","name":"CVE-2026-80797","record":{"aliases":["AZL-99494","BELL-CVE-2026-80797","DEBIAN-CVE-2026-80797","GHSA-4h9c-xj6x-wv3f","UBUNTU-CVE-2026-80797"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel NFC driver","requires_auth":"none","summary":"A memory leak in the Linux kernel NFC driver allows local attackers to cause denial of service by triggering device removal with queued fragments.","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\nnfc: pn533: purge fragmented skbs during cleanup\n\npn53x_common_clean() purges resp_q before freeing the common PN533 state,\nbut it leaves fragment_skb untouched.
