Technical Description
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().
Remediation
Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
