- Summary
- ntfs3: Allocate iomap inline_data using alloc_page
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
ntfs3: Allocate iomap inlinedata using allocpage
This fixes a BUG reported in iomapwriteendinline: iomapinlinedatavalid checks that the inlinedata fits within a page. If the inlinedata 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.
