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-2026-80867 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-2026-80867/ (Markdown: https://insights.sbomify.com/CVE-2026-80867/index.md)","id":"CVE-2026-80867","markdown":"https://insights.sbomify.com/CVE-2026-80867/index.md","name":"CVE-2026-80867","record":{"aliases":["BELL-CVE-2026-80867","DEBIAN-CVE-2026-80867","GHSA-6r46-6gmq-67cv","UBUNTU-CVE-2026-80867"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"Local attackers can bypass kernel lockdown restrictions on Alpha architecture to access PCI BARs, potentially enabling DMA attacks.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"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\nalpha/PCI: Add security_locked_down() check to pci_mmap_resource()\n\nCurrently, Alpha's pci_mmap_resource() does not check\nsecurity_locked_down(LOCKDOWN_PCI_ACCESS) before allowing userspace to mmap\nPCI BARs.\n\nThe generic version has had this check since commit eb627e17727e (\"PCI:\nLock down BAR access when the kernel is locked down\") to prevent DMA\nattacks when the kernel is locked down.\n\nAdd the same check to Alpha's pci_mmap_resource().","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"alpha/PCI: Add security_locked_down() check to pci_mmap_resource()","id":"CVE-2026-80867","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"ntfs3: Allocate iomap inline_data using alloc_page","id":"CVE-2026-80868"},"packages":[],"prev":{"headline":"tipc: avoid busy looping in tipc_exit_net()","id":"CVE-2026-80866"},"products":["Linux"],"published":"2026-09-04","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-09-04","vendors":["Linux"]},"summary":"Local attackers can bypass kernel lockdown restrictions on Alpha architecture to access PCI BARs, potentially enabling DMA attacks.","url":"https://insights.sbomify.com/CVE-2026-80867/"}
