| Vector | AV:A/AC:L/Au:S/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw exists in the Linux kernel's NTFS3 implementation related to uninitialized memory after a failed
mi read operation within mi format new. The issue stems from the ntfs get bh() function potentially receiving a buffer from sb getblk() that is not up-to-date. This could lead to adding a buffer containing uninitialized data to the Master File Table (MFT) record, triggering a Kernel Memory Safety Administration (KMSAN) error when attempting to load that record. The fix involves ensuring the buffer is marked as up-to-date before being used.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
