CVE-2026-64533

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: validate lcnsfollow in logreplay conversion logreplay converts DIRPAGEENTRY32 records into DIRPAGEENTRY records when replaying version 0 restart tables. During this conversion, the memmove length is derived directly fro...

CVE-2026-64431

A flaw was found in the Linux kernel's NTFS file system driver. A remote attacker could exploit this vulnerability by providing a specially crafted NTFS image, leading to out-of-bounds memory access. This memory corruption can cause the system to crash, resulting in a denial of service...

CVE-2026-64532

Summary: CVE-2026-64532 affects the Linux kernel ntfs3 path. Filesystem code in UpdateRecordDataRoot/UpdateRecordDataAllocation bound checks for on-disk NTFS_DE view.data_off are missing when memmoving data, allowing potential out-of-bounds writes. The issue arises because memmove destinations us...
