CVE-2022-49113

CVE-2022-49113 — In the Linux kernel, a refcount leak in powerpc/secvar, specifically in format_show(), is fixed. The leak can occur when format_show returns failure in multiple paths. The mitigation is the unified management of of_node_put to correct the leak. The available connected sources con...
