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().","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/3bf6f5e2e1007d38a5f35bd37e94ab645a0c40bc","tags":[]},{"url":"https://git.kernel.org/stable/c/6b78786ee7260d9818cf1d7a245b7a655ef83076","tags":[]},{"url":"https://git.kernel.org/stable/c/6bbbd7b719233645a5c120557a9ca1422e6b7a48","tags":[]},{"url":"https://git.kernel.org/stable/c/f7a1064cce3b100b54780c68529176232d8eb01e","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
