CVE-2026-72209

CVE-2026-72209 concerns the Linux kernel NTFS attribute value handling. The fix adds a shared attribute value validator and applies it before any lookup path can return an attribute (including AT_UNUSED). The validator enforces bounds for resident values, minimum resident sizes, checks variable-l...

CVE-2026-72197 fs/ntfs3: bound DeleteIndexEntryAllocation memmove length

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: bound DeleteIndexEntryAllocation memmove length In doaction's DeleteIndexEntryAllocation case, e-size comes from an on-disk INDEXBUFFER entry. When e-size makes e + e-size point past hdr + hdr-used, PtrOffsete1,...

CVE-2026-72197 fs/ntfs3: bound DeleteIndexEntryAllocation memmove length

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: bound DeleteIndexEntryAllocation memmove length In doaction's DeleteIndexEntryAllocation case, e-size comes from an on-disk INDEXBUFFER entry. When e-size makes e + e-size point past hdr + hdr-used, PtrOffsete1,...

CVE-2026-72197

The CVE-2026-72197 issue affects the Linux kernel, specifically the fs/ntfs3 path for DeleteIndexEntryAllocation. The root cause is that e->size can cause an overlong memmove when e + e->size points past hdr + hdr->used, leading to a dangerous memmove length. A corresponding guard alread...
