If kvm_init() fails its\nresult is returned directly, but since module_init() does not run the\nmodule_exit() stuff on failure, so kvm_loongarch_env_exit() is never\ncalled and those resources are leaked.\n\nSo call kvm_loongarch_env_exit() when kvm_init() fails, matching the\nteardown-on-failure pattern used by riscv_kvm_init().","state":0,"publishedAt":"2026-09-16T10:32:07.278+00:00","modifiedAt":"2026-10-19T08:54:42.797+00:00","affected":[{"ecosystem":"Vendor
