CVE-2026-53029

A flaw was found in the Linux kernel's ntfs3 filesystem driver. This vulnerability occurs due to an uninitialized local variable lcn when handling zero-length data during I/O operations. An attacker could potentially exploit this flaw to cause a denial of service or information disclosure due to...

CVE-2026-53027

A flaw was found in the Linux kernel's fs/ntfs3 component. When handling compressed or sparse attributes with frame-aligned clusters, a missing run load for vcn0 can occur if vcn0 resides in a different attribute segment. This oversight can lead to a kernel warning WARNON1 during a run lookup,...

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: prevent uninitialized lcn caused by zero len syzbot reported a uninit-value in ntfsiomapbegin 1. Since runs was not touched yet, runlookupentry immediately fails and returns false, which makes the value of "len" 0...

EUVD-2026-38895

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: fix missing run load for vcn0 in attrdatagetblocklocked When a compressed or sparse attribute has its clusters frame-aligned, vcn is rounded down to the frame start using cmask, which can result in vcn != vcn0. In this...

CVE-2026-53027

The CVE concerns the Linux kernel ntfs3 code path in attr_data_get_block_locked, where a compressed or sparse attribute with frame-aligned clusters can cause vcn to be misaligned (vcn != vcn0). If vcn0 resides in a different attribute segment than vcn, the in-memory run list may not have loaded t...

CVE-2026-53023

CVE-2026-53023 affects Linux kernel ntfs3: ntfs_fill_super() converts the on-disk volume label from UTF-16 to UTF-8 and stores it in sbi->volume.label, but utf16s_to_utf8s() does not append a NUL terminator. If the converted label fills the fixed buffer, ntfs3_label_show() could read past the ...
