NVD Description

Note: Versions mentioned in the description apply only to the upstream linux-virt-doc package and not the linux-virt-doc package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

exfat: fix the new buffer was not zeroed before writing

Before writing, if a buffer_head marked as new, its data must be zeroed, otherwise uninitialized data in the page cache will be written.

So this commit uses folio_zero_new_buffers() to zero the new buffers before ->write_end().
