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-2026-89909/ (Markdown: https://insights.sbomify.com/CVE-2026-89909/index.md)","id":"CVE-2026-89909","markdown":"https://insights.sbomify.com/CVE-2026-89909/index.md","name":"CVE-2026-89909","record":{"aliases":["BELL-CVE-2026-89909","DEBIAN-CVE-2026-89909","GHSA-9g5j-xh66-prwm","UBUNTU-CVE-2026-89909"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"unknown","non_default_config":false,"product_category":"Linux kernel KVM","requires_auth":"none","summary":"A resource leak in the Linux kernel's LoongArch KVM initialization allows local attackers to cause memory exhaustion and denial of service.","user_interaction":"not_required","vuln_class":"other"},"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\nLoongArch: KVM: Free init resources if kvm_init() fails\n\nkvm_loongarch_init() calls kvm_loongarch_env_init() to allocate the\nper-CPU kvm_context (vmcs) and kvm_loongarch_ops and to register the\nperf callbacks, and then calls kvm_init().
