AI-suggested
A patch is available and has been applied in the Linux kernel after version 6.19. Users should update to a fixed kernel version containing the commits f7edab0cee03a1cbe0e55a7bcab8d2d8b6b74278, dac871d833b09495198dcac81d2ebaa8db11acbc, or d977b979081ef2585a15453f309a6311c95ede02. Since this is a kernel-level fix, updating the kernel is the recommended remediation. The vendor manages remediation for this cloud-hosted service if applicable.
Description
A memory leak vulnerability in the Linux kernel's NTFS3 filesystem driver was fixed. The issue occurs in the ntfs_fill_super() function where the fs_private pointer is set to NULL without freeing the allocated memory, causing a leak of the ntfs_mount_options structure. This results in kmemleak reports during mounting operations. The fix involves proper cleanup using a helper function and avoiding unnecessary nullification of the pointer.
