"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nntfs: fix kmap_local_page() usage in compress\n\nSeveral compressed I/O paths discard the address returned by\nkmap_local_page() and later access or unmap the page using page_address().\nThis is invalid for highmem pages, and local mappings must also be unmapped\nusing the address returned by kmap_local_page().\n\nMap each destination page in ntfs_decompress() only while producing the\ncurrent sub-block. Use memcpy_from_page(), memcpy_to_page(), and\nmemzero_page() for the other page accesses. Remove unnecessary local\nmappings from ntfs_write_cb(), where pages are accessed through the vmap()\nmapping."
