cve 2025 68728

CVE-2025-68728 is a Linux kernel vulnerability in the ntfs3 driver, specifically a KMSAN-reported uninitialized-memory condition in the mi_format_new function. The bug could cause uninitialized buffer contents to be added to internal metadata records after a failed mi_read operation. The upstream fix ensures the buffer is deterministically initialized or overwritten before being marked up-to-date. This tag covers discussions about the CVE, its impact on kernel memory safety, and the patch that resolves the issue. Topics include the ntfs3 driver, KMSAN, kernel memory initialization, and related troubleshooting for Linux systems using NTFS.
