CVE-2026-42616

A flaw was found in NTFS-3G. An attacker can trigger a heap buffer overflow in the ntfscat utility by providing a specially crafted NTFS filesystem image. When the utility attempts to read a file from the malicious image, heap memory is corrupted, which can lead to a Denial of Service DoS crash o...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Added a depth limit to indxfindbuffer to prevent stack overflow. indxfindbuffer recursively descends the B+ tree index without a depth limit. A malicious NTFS image with circular index node references causes unbounded...

Astra Linux – Vulnerability in grub2

A out-of-bounds write flaw was discovered in grub2’s NTFS filesystem driver. This issue may allow an attacker to present a specially crafted NTFS filesystem image, resulting in corruption of grub’s heap metadata. In some cases, the attack may also corrupt the UEFI firmware heap metadata. As a...

DEBIAN-CVE-2026-89614

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...

DEBIAN-CVE-2026-89611

In the Linux kernel, the following vulnerability has been resolved: ntfs: validate non-resident attribute offsets ntfsattrupdatemeta shifts the attribute name when converting between non-sparse and sparse attributes. Converting to sparse also adds the compressedsize field before the name and...

CVE-2026-89614

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...

In the Linux kernel, the following vulnerability has been resolved: ntfs: reject invalid empty mapping pairs Reject an attribute with empty mapping pairs if it has inconsistent highest VCN and size...

UBUNTU-CVE-2026-89610

In the Linux kernel, the following vulnerability has been resolved: ntfs: verify run length exceeding volume boundary The mapping pairs decoder validates that the starting LCN is within the volume but does not check if the run extends beyond the volume boundary. A malformed NTFS image with 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...

CVE-2026-89614

CVE-2026-89614 affects the Linux kernel's NTFS file system driver . The flaw is in ntfs_cluster_alloc(), which bounds its free-cluster bitmap scan by the size of the on-disk $Bitmap rather than by the volume's actual cluster count (nr_clusters). Because these are independent quantities, a special...
