CVE-2026-89779

A flaw was found in the Linux kernel's ntfs3 filesystem driver. This vulnerability allows a local attacker to craft an Extended Attribute EA record with an undersized ef-size value. When processed, this can lead to an out-of-bounds read, resulting in the disclosure of sensitive heap memory to...

CVE-2026-90200

A flaw was found in the Linux kernel's NTFS3 file system driver. An integer overflow vulnerability exists in the Multi-File Table MFT cluster validation logic. When processing a specially crafted boot sector, the driver fails to properly validate MFT cluster numbers due to an integer overflow...

CVE-2026-90199

A flaw was found in the Linux kernel's fs/ntfs3 file system driver. An issue in the mienumattr function, responsible for validating virtual cluster numbers VCNs for non-resident attributes, could allow a local attacker to craft a malformed on-disk attribute. This malformed attribute, with an...

ROS-20261012-73-0232

The vulnerability of the fs/ntfs3 components in the Linux operating system is related to incorrect data input used as a condition for loop execution. Exploiting this vulnerability can allow an attacker to cause a service failure...

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: A slab-out-of-bounds read issue in DeleteIndexEntryRoot has been fixed. In the DeleteIndexEntryRoot function of the doaction function, the entry size esize is retrieved from the log record without proper bounds checking...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ntfs3: Boundary checks for the buffer were added to rununpack. rununpack checks runbuf runlast at the beginning of the while loop. However, it then reads sizesize and offsetsize bytes via rununpacks64, without verifying that thes...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ntfs3: Treating $Extend records as regular files. Since the commit af153bb63a33 "vfs: catching invalid modes in mayopen" requires that any inode be of one of the types SIFDIR/SIFLNK/SIFREG/SIFCHR/SIFBLK/SIFIFO/SIFSOCK, use SIFREG...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: fs/ntfs3: Validates buffer length during parsing of indexes. The indxread function is called when performing NTFS directory operations that require more information from the index buffers. This adds a sanity check to ensure th...
