  "description": "In the Linux kernel, the following vulnerability has been resolved:  ntfs: fix off-by-one page overflow in ntfs_decompress()  The per-token range check in ntfs_decompress() uses  \tif (cb \u003E= cb_sb_end || dp_addr \u003E dp_sb_end) \t\tbreak;  so dp_addr == dp_sb_end falls through to the symbol copy \u0060*dp_addr\u002B\u002B = *cb\u002B\u002B\u0060, writing one byte past the destination page.  Since NTFS_SB_SIZE == PAGE_SIZE the destination is a single page, so the byte lands in the adjacent page, and *dest_ofs is left one past the sub-block end (the later \u0060*dest_ofs \u0026= ~PAGE_MASK\u0060 then yields 1, not 0, so the page is never finalized and later sub-blocks keep writing further past it).  A corrupted compressed $DATA attribute thus produces a bounded run of out-of-bounds writes when the file is read.  Break as soon as dp_addr reaches dp_sb_end; a full sub-block still completes, as its final copy advances dp_addr to exactly dp_sb_end.",
