      "title": "ntfs: free volume-wide resources on fill_super failure",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nntfs: free volume-wide resources on fill_super failure\n\nntfs_fill_super()'s err_out_now path frees only the volume struct via\nkfree(vol), leaving several vol-owned allocations behind on every mount\nfailure:\n\n  - vol->nls_map, loaded by ntfs_init_fs_context() via\n    load_nls_default() (or replaced by an explicit nls= option in\n    ntfs_parse_param()), is never unload_nls()'d.\n\n  - vol->volume_label, allocated by load_system_files() through\n    ntfs_ucstonls() once the $Volume name attribute has been parsed, is\n    not released by load_system_files()'s own error labels nor by the\n    fill_super() inline cleanup that only runs on d_make_root()\n    failure.  Any later failure inside load_system_files() leaks it.\n\n  - vol->lcn_empty_bits_per_page was kvfree()'d in\n    unl_upcase_iput_tmp_ino_err_out_now without clearing the pointer,\n    so it could not be folded into a single common cleanup.\n\nBecause the failure paths never call ntfs_volume_free() and never reach\nthe d_make_root() inline cleanup block (it sits above the label and is\njumped over by the load_system_files() / kvmalloc failure gotos), these\nresources accumulate per failed mount attempt with no chance of\nrecovery short of unloading the module.  This is a silent leak: the\ninodes loaded prior to failure remain hashed but generic_shutdown_super()\nskips evict_inodes() when sb->s_root is unset, so no CHECK_DATA_CORRUPTION\nwarning is emitted either.\n\nMove the per-volume frees down to err_out_now and drop the\nlcn_empty_bits_per_page kvfree() from the upper label so the cleanup is\nperformed exactly once on every failure path.  Using unconditional\nkvfree() / kfree() / unload_nls() is safe because they all accept NULL\nand the upper labels that previously freed nls_map (the d_make_root()\ninline cleanup) already clear the pointer.",
