In the Linux kernel, the following vulnerability has been resolved: ntfs: fix hole runlist memory leak in insert range error path ntfs_non_resident_attr_insert_range() allocates hole_rl before mapping the whole runlist. If ntfs_attr_map_whole_runlist() fails, the error path drops ni->runlist.lock and returns without freeing hole_rl. This leaks memory of sizeof(*hole_rl) * 2 bytes. Fix this memory leak by freeing hole_rl before returning from that error path, matching the later error paths in the same function.

A flaw was found in the Linux kernel's NTFS file system driver. When handling non-resident attributes, a memory leak occurs in the `ntfs_non_resident_attr_insert_range()` function. If the mapping of the runlist fails, allocated memory for `hole_rl` is not properly released. This can lead to resource exhaustion over time, potentially resulting in a Denial of Service (DoS) for the system.
