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 GSD-2021-1002164 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- Kernel (Linux): affected all versions; no fix listed\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/GSD-2021-1002164/ (Markdown: https://insights.sbomify.com/GSD-2021-1002164/index.md)","id":"GSD-2021-1002164","markdown":"https://insights.sbomify.com/GSD-2021-1002164/index.md","name":"GSD-2021-1002164","record":{"aliases":[],"analysis":{"component_type":"kernel","fix_type":"upgrade","impacts":["privilege_escalation","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux Kernel KVM","requires_auth":"high_privilege","summary":"A refcount error in KVM arm64 stage-2 page tables may allow local attackers to cause memory corruption, leading to privilege escalation or system crashes.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"KVM: arm64: Fix host stage-2 PGD refcount\n\nThis is an automated ID intended to aid in discovery of potential security vulnerabilities.
