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-2021-1002841/ (Markdown: https://insights.sbomify.com/GSD-2021-1002841/index.md)","id":"GSD-2021-1002841","markdown":"https://insights.sbomify.com/GSD-2021-1002841/index.md","name":"GSD-2021-1002841","record":{"aliases":[],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"unknown","non_default_config":false,"product_category":"Linux kernel","requires_auth":"unknown","summary":"A use-after-free bug in the Linux kernel's OP-TEE driver could allow attackers to execute arbitrary code or cause a denial of service.","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":"tee: optee: Fix incorrect page free bug\n\nThis is an automated ID intended to aid in discovery of potential security vulnerabilities.
