Vulnerability from github – Published: 2026-09-04 18:31 – Updated: 2026-09-04 18:31

Details

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.
