NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek-debug package and not the kernel-uek-debug package as distributed by Oracle. See How to fix? for Oracle:9 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().
