## Overview

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

fs: Fix uninitialized 'offp' in statmount_string()

In statmount_string(), most flags assign an output offset pointer (offp)
which is later updated with the string offset. However, the
STATMOUNT_MNT_UIDMAP and STATMOUNT_MNT_GIDMAP cases directly set the
struct fields instead of using offp. This leaves offp uninitialized,
leading to a possible uninitialized dereference when *offp is updated.

Fix it by assigning offp for UIDMAP and GIDMAP as well, keeping the code
path consistent.
