Echo: linux: security update to 6.1.158-1

high Tenable Cloud Security Plugin ID 457439

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: fs: ntfs3: Fix integer overflow in
run_unpack() The MFT record relative to the file being opened contains its runlist, an array containing
information about the file's location on the physical disk. Analysis of all Call Stack paths showed that
the values of the runlist array, from which LCNs are calculated, are not validated before run_unpack
function. The run_unpack function decodes the compressed runlist data format from MFT attributes (for
example, $DATA), converting them into a runs_tree structure, which describes the mapping of virtual
clusters (VCN) to logical clusters (LCN). The NTFS3 subsystem also has a shortcut for deleting files from
MFT records - in this case, the RUN_DEALLOCATE command is sent to the run_unpack input, and the function
logic provides that all data transferred to the runlist about file or directory is deleted without
creating a runs_tree structure. Substituting the runlist in the $DATA attribute of the MFT record for an
arbitrary file can lead either to access to arbitrary data on the disk bypassing access checks to them
(since the inode access check occurs above) or to destruction of arbitrary data on the disk. Add overflow
check for addition operation. Found by Linux Verification Center (linuxtesting.org) with SVACE.
(CVE-2025-40068)
