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-2026-53027

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...
