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-2026-53027

CVE-2026-53027 affects the Linux kernel's fs/ntfs3 component. A missing load of the vcn0 runs when a compressed/sparse attribute is frame-aligned can leave vcn0 in a different attribute segment than vcn, causing run_lookup_entry() to return SPARSE_LCN and triggering WARN_ON(1). The documented fix...
