If parsing a child fails, the failed child is\nnot counted in nr_children and the parent may be left with a children array\nthat bl_free_device() will not release when nr_children is zero.\n\nRelease the failed child and the already parsed children before returning the\nerror.  Also make bl_free_device() release the child array whenever the\nchildren pointer is set, so that partially initialised concat or stripe\ndevices are cleaned up correctly.\n\nbl_parse_scsi() can also fail after assigning d->bdev_file and dropping the\nfile reference.  Clear the pointer after fput() so that an outer cleanup path\ndoes not put it again.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/1e1c36b206c659cf94c6755a1d821ed1babd32bc","tags":[]},{"url":"https://git.kernel.org/stable/c/23e4162405c456ce12c772d5882d306135e828ae","tags":[]},{"url":"https://git.kernel.org/stable/c/8a2494964edac2a13e82441c2bf887548dc3be0b","tags":[]},{"url":"https://git.kernel.org/stable/c/c056f817e4200fb18079d5052c273a22f191ff0a","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
