AI-suggested
A fix is available that properly frees the allocated memory in the error path of the ntfs_non_resident_attr_insert_range() function. Users should update to Linux kernel versions that include this fix. Since this is a low-severity memory leak, no additional mitigation is required beyond applying the official patch.
Description
A memory leak vulnerability was identified and fixed in the Linux kernel's NTFS driver. The flaw occurs in the ntfs_non_resident_attr_insert_range() function where allocated memory for a hole runlist is not freed upon a specific error condition, causing a small memory leak. This issue affects certain versions of the Linux kernel and has been resolved by ensuring proper memory deallocation in the error path.
