Linux Distros Unpatched Vulnerability : CVE-2026-53029

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - fs/ntfs3: prevent uninitialized lcn caused by zero len syzbot reported a uninit-value in ntfsiomapbegin 1. Since runs was not touched yet, runlookupentry...

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,...

CVE-2026-53029

CVE-2026-53029: In the Linux kernel’s ntfs3 codepath, an uninitialized LCN could be triggered due to a zero-length path in ntfs_iomap_begin. The bug arises because run_lookup_entry() can fail and leave *len and the new value/err at 0, causing attr_data_get_block_locked() to take an ok path before...

CVE-2026-53029 fs/ntfs3: prevent uninitialized lcn caused by zero len

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...

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 ...
