+Subject: [PATCH] Cap B tree depth in ntfs_index_walk_down to MAX_PARENT_VCN.
+
+ntfs_index_walk_down() incremented ictx->pindex and wrote into
+ictx->parent_pos[] / parent_vcn[] (both sized MAX_PARENT_VCN) without
+checking the bound.  A B+tree deeper than MAX_PARENT_VCN levels then
+overflowed both arrays and since parent_vcn[32] overlaps the pindex
+field the OOB write gave an attacker control over the next iteration's
+offset and value.
+
+Thanks to Alexandro Calo' from Nozomi Networks Labs for reporting this
+issue.
