    "summary": "In the Linux kernel, the following vulnerability has been resolved: apparmor: release exe file resources on path failure get_current_exe_path() takes both an exe_file reference and a path reference before resolving the path name. If aa_path_name() failed, it returned immediately and leaked both references. Route the failure through the common cleanup path so fput() and path_put() always run after the references are acquired.",
