CVE-2026-89614

A flaw was found in the Linux kernel's NTFS file system driver. This vulnerability occurs because the free-cluster bitmap scan is not properly bounded to the volume size. A specially crafted NTFS image, where the bitmap covers more clusters than the volume actually has, can lead to an out-of-boun...

CVE-2026-89614

This vulnerability affects the Linux kernel NTFS filesystem driver. The root cause is a slab out-of-bounds read in ntfs_cluster_alloc(): the free-cluster bitmap scan is bounded by the on-disk $Bitmap size, but the in-memory array vol->lcn_empty_bits_per_page is sized from vol->nr_clusters a...

CVE-2026-89614 ntfs: bound the free-cluster bitmap scan to the volume

In the Linux kernel, the following vulnerability has been resolved: ntfs: bound the free-cluster bitmap scan to the volume vol-lcnemptybitsperpage is sized from vol-nrclusters at mount, but ntfsclusteralloc bounds its scan of that array by the size of $Bitmap. Those are independent on-disk...
