In the Linux kernel, the following vulnerability has been resolved:
ntfs3: Allocate iomap inline_data using alloc_page
This fixes a BUG reported in iomap_write_end_inline:
iomap_inline_data_valid checks that the inline_data fits within
a page. If the inline_data is allocated with kmemdup there's no
guarantee that it's page-aligned, so the check sometimes fails.
Allocate it with alloc_page to ensure it's page-aligned.
