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-2026-92505 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-2026-92505/ (Markdown: https://insights.sbomify.com/CVE-2026-92505/index.md)","id":"CVE-2026-92505","markdown":"https://insights.sbomify.com/CVE-2026-92505/index.md","name":"CVE-2026-92505","record":{"aliases":["BELL-CVE-2026-92505","DEBIAN-CVE-2026-92505","GHSA-2mxc-qwhf-8gfr","UBUNTU-CVE-2026-92505"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel","requires_auth":"high_privilege","summary":"A local attacker with debugfs access can trigger undefined behavior in the AMD IOMMU driver, potentially causing 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\niommu/amd: Fix undefined behavior in devid_write debugfs function\n\nWhen for_each_pci_segment() loop completes without finding a matching\nsegment, the pci_seg pointer is not NULL but points to an invalid memory\nlocation (the list head).
