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-2026-80651 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-2026-80651/ (Markdown: https://insights.sbomify.com/CVE-2026-80651/index.md)","id":"CVE-2026-80651","markdown":"https://insights.sbomify.com/CVE-2026-80651/index.md","name":"CVE-2026-80651","record":{"aliases":["DEBIAN-CVE-2026-80651","GHSA-m48c-q8rx-qxxm","UBUNTU-CVE-2026-80651"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A null pointer dereference in the Linux kernel's SEV TSM driver allows local attackers to cause a system crash.","user_interaction":"not_required","vuln_class":"null_dereference"},"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\ncrypto: ccp/sev-dev-tsm - bail out early when pdev-\u003ebus is NULL\n\ndsm_create() initially checks pdev-\u003ebus when computing segment_id:\n\n\tu8 segment_id = pdev-\u003ebus ? pci_domain_nr(pdev-\u003ebus) : 0;\n\nBut the next two lines unconditionally dereference pdev-\u003ebus via\npcie_find_root_port() and especially pci_dev_id(pdev), which expands\nto PCI_DEVID(dev-\u003ebus-\u003enumber, dev-\u003edevfn).
