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()."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["arch/loongarch/kvm/main.c"],"versions":[{"version":"2bd6ac68726131da32ace9717aa63ff68cf6605c","lessThan":"6bbbd7b719233645a5c120557a9ca1422e6b7a48","status":"affected","versionType":"git"},{"version":"2bd6ac68726131da32ace9717aa63ff68cf6605c","lessThan":"6b78786ee7260d9818cf1d7a245b7a655ef83076","status":"affected","versionType":"git"},{"version":"2bd6ac68726131da32ace9717aa63ff68cf6605c","lessThan":"3bf6f5e2e1007d38a5f35bd37e94ab645a0c40bc","status":"affected","versionType":"git"},{"version":"2bd6ac68726131da32ace9717aa63ff68cf6605c","lessThan":"f7a1064cce3b100b54780c68529176232d8eb01e","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["arch/loongarch/kvm/main.c"],"versions":[{"version":"6.7","status":"affected"},{"version":"0","lessThan":"6.7","status":"unaffected","versionType":"semver"},{"version":"6.12.110","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.51","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.5","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3-rc2","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.7","versionEndExcluding":"6.12.110"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.7","versionEndExcluding":"6.18.51"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.7","versionEndExcluding":"7.2.5"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.7","versionEndExcluding":"7.3-rc2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/6bbbd7b719233645a5c120557a9ca1422e6b7a48"},{"url":"https://git.kernel.org/stable/c/6b78786ee7260d9818cf1d7a245b7a655ef83076"},{"url":"https://git.kernel.org/stable/c/3bf6f5e2e1007d38a5f35bd37e94ab645a0c40bc"},{"url":"https://git.kernel.org/stable/c/f7a1064cce3b100b54780c68529176232d8eb01e"}],"title":"LoongArch: KVM: Free init resources if kvm_init() fails","x_generator":{"engine":"bippy-1.2.0"}}}}
