  "description": "In the Linux kernel, the following vulnerability has been resolved:  fs/ntfs3: Fix slab-out-of-bounds in r_page  When PAGE_SIZE is 64K, if read_log_page is called by log_read_rst for the first time, the size of *buffer would be equal to DefaultLogPageSize(4K).But for *buffer operations like memcpy, if the memory area size(n) which being assigned to buffer is larger than 4K (log-\u003Epage_size(64K) or bytes(64K-page_off)), it will cause an out of boundary error.
