  "description": "In the Linux kernel, the following vulnerability has been resolved:  RDMA/rtrs: Fix use-after-free in path file creation cleanup  In the error path of rtrs_srv_create_path_files(), the sysfs root folders may already have been created and srv_path-\u003Ekobj may already have been initialized. If a later step fails, the cleanup currently calls kobject_put(\u0026srv_path-\u003Ekobj) before rtrs_srv_destroy_once_sysfs_root_folders(srv_path).  kobject_put() may drop the last reference to srv_path-\u003Ekobj and invoke the release callback, rtrs_srv_release(), which frees srv_path. The following call to rtrs_srv_destroy_once_sysfs_root_folders(srv_path) then dereferences srv_path internally to access srv_path-\u003Esrv, resulting in a use-after-free.  This failure path is reached before rtrs_srv_create_path_files() returns success, so the successful-path lifetime handling is not involved.  Fix this by destroying the sysfs root folders before calling kobject_put(\u0026srv_path-\u003Ekobj), so srv_path is still valid while the helper accesses it.  This issue was found by a static analysis tool I am developing.",
