It can only be exploited from the same machine or local network.\nExploitation: There is no known exploitation of GSD-2021-1001606 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-2021-1001606/ (Markdown: https://insights.sbomify.com/GSD-2021-1001606/index.md)","id":"GSD-2021-1001606","markdown":"https://insights.sbomify.com/GSD-2021-1001606/index.md","name":"GSD-2021-1001606","record":{"aliases":[],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"unknown","summary":"A use-after-free vulnerability in the Linux kernel's blk-cgroup subsystem could allow local attackers to execute arbitrary code or escalate privileges.","user_interaction":"unknown","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"blk-cgroup: fix UAF by grabbing blkcg lock before destroying blkg pd\n\nThis is an automated ID intended to aid in discovery of potential security vulnerabilities.
