Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Fixed the missing iop in ntfsreadmft. There is a null pointer dereference issue because iop == NULL. The bug occurs because we do not initialize iop for records in $Extend$...

Astra Linux - уязвимость в ntfs-3g

In NTFS-3G versions before 2021.8.22, when a specially crafted NTFS attribute is provided to the function ntfsgetattributevalue, a heap buffer overflow can occur, allowing for memory disclosure or denial of service. The vulnerability is caused by an out-of-bound buffer access, which can be...

Astra Linux - уязвимость в ntfs-3g

NTFS-3G versions prior to 2021.8.22 may experience a heap buffer overflow when a specially crafted NTFS attribute is set up using the function ntfsattrsetupflag. This could allow code execution and an escalation of privileges...

Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Added a null pointer check for inode operations This adds a sanity check for the iop pointer of the inode, which is returned after reading the Root directory MFT record. We should check that the iop is valid before...

CVE-2022-50841

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Add overflow check for attribute size The offset addition could overflow and pass the used size check given an attribute with very large size e.g., 0xffffff7f while parsing MFT attributes. This could lead to out-of-boun...

EUVD-2023-60368

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Fix memory leak if ntfsreadmft failed Label ATTRROOT in ntfsreadmft sets isroot = true and ni-niflags |= NIFLAGDIR, then next attr will goto label ATTRALLOC and alloc ni-dir.allocrun. However two states are not always...

CVE-2022-50739

The connected docs confirm CVE-2022-50739 affects the Linux kernel's ntfs3 filesystem. Root cause: missing validation of inode's i_op pointer after reading the Root directory MFT, which can cause a NULL pointer dereference when mounting an image with a malformed Root directory MFT record. The fix...

Analysis of all Call Stack paths...

CVE-2025-40068

The CVE-2025-40068 entry is supported by multiple connected advisories confirming a concrete Linux kernel issue in the ntfs3 subsystem. The vulnerability stems from an overflow in the run_unpack() path that decodes the MFT runlist (used to map virtual clusters to logical clusters). Because values...

CVE-2022-50336 fs/ntfs3: Add null pointer check to attr_load_runs_vcn

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Add null pointer check to attrloadrunsvcn Some metadata files are handled before MFT. This adds a null pointer check for some corner cases that could lead to NPD while reading these metadata files for a malformed NTFS...

CVE-2022-50336

CVE-2022-50336 – Linux kernel (fs/ntfs3) Root cause: a missing null pointer check in attr_load_runs_vcn when parsing certain NTFS metadata before MFT could permit a kernel NULL pointer dereference on malformed images. Impact: kernel crash/free crash (NPD) resulting from NULL dereference in ntfs-r...
