"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nocfs2: reject non-inline dinodes with i_size and zero i_clusters\n\nOn a volume mounted without OCFS2_FEATURE_INCOMPAT_SPARSE_ALLOC, a\nnon-inline regular file with non-zero i_size and zero i_clusters is\nstructurally malformed: the extent map declares no allocated clusters yet\nthe size header claims content exists. Keep rejecting that shape, but\nexpress it through a shared predicate so the same invariant is available\nto normal inode reads and online filecheck.\n\nThe same zero-cluster shape is also malformed for non-inline directories. \nocfs2 directory growth allocates backing storage before advancing i_size,\nand ocfs2_dir_foreach_blk_el() later walks until ctx->pos reaches\ni_size_read(inode). A forged directory dinode with a huge i_size and no\nclusters would repeatedly fail on holes while advancing through the\nclaimed size.\n\nSparse regular files remain exempt: on sparse-alloc volumes, truncate can\nlegitimately grow i_size without allocating clusters. System inodes and\ninline-data dinodes also retain their separate storage rules.\n\nMirror the check in ocfs2_filecheck_validate_inode_block() as well. \nfilecheck reports through its own error namespace, so malformed\nsize/cluster state is logged as a filecheck invalid-inode result rather\nthan via ocfs2_error(), but it must not proceed into\nocfs2_populate_inode()."
