CVE-2025-68212

Description

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, theSTATMOUNT_MNT_UIDMAP and STATMOUNT_MNT_GIDMAP cases directly set thestruct 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 codepath consistent.
