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-2026-80687 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-2026-80687/ (Markdown: https://insights.sbomify.com/CVE-2026-80687/index.md)","id":"CVE-2026-80687","markdown":"https://insights.sbomify.com/CVE-2026-80687/index.md","name":"CVE-2026-80687","record":{"aliases":["BELL-CVE-2026-80687","DEBIAN-CVE-2026-80687","GHSA-fh38-x9qp-g22j","UBUNTU-CVE-2026-80687"],"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":"low_privilege","summary":"A missing lock release in the Linux kernel iommufd driver allows local attackers to cause a deadlock and denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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\niommufd/viommu: Release the igroup lock on the vdevice_size error path\n\niommufd_vdevice_alloc_ioctl() takes idev-\u003eigroup-\u003elock, then validates the\ndriver's vdevice_size against the core structure size with a WARN_ON_ONCE.\nOn failure that guard jumps to out_put_idev, below out_unlock_igroup, so it\nskips the mutex_unlock(), leaving the igroup lock held and deadlocking the\nnext vDEVICE operation on that group.\n\nJump to out_unlock_igroup instead.","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":"iommufd/viommu: Release the igroup lock on the vdevice_size error path","id":"CVE-2026-80687","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"riscv: drop __init from vec_check_unaligned_access_speed_all_cpus","id":"CVE-2026-80688"},"packages":[],"prev":{"headline":"mm: migrate_device: fix pte_pfn/pte_dirty called on non-present PTE","id":"CVE-2026-80686"},"products":["Linux"],"published":"2026-08-28","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":"2026-08-28","vendors":["Linux"]},"summary":"A missing lock release in the Linux kernel iommufd driver allows local attackers to cause a deadlock and denial of service.","url":"https://insights.sbomify.com/CVE-2026-80687/"}
