CVE-2026-53015

A flaw was found in the Linux kernel's erofs filesystem. On 32-bit platforms, the lcn variable, used for logical cluster numbers, was defined as a 32-bit integer. This could lead to truncation when calculating offsets larger than 4 Gigabytes GiB, potentially causing incorrect data handling within...

Linux Distros Unpatched Vulnerability : CVE-2026-53015

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - erofs: unify lcn as u64 for 32-bit platforms As sashiko reported 1, lcn was typed as unsigned long or unsigned int sometimes, which is only 32 bits wide on 32-b...

CVE-2026-53027

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-2026-53029

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-2026-53027 fs/ntfs3: fix missing run load for vcn0 in attr_data_get_block_locked()

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...
