CVE-2026-23434

mtd: rawnand: serialize lock/unlock against other NAND operations

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

mtd: rawnand: serialize lock/unlock against other NAND operations

nand_lock() and nand_unlock() call into chip->ops.lock_area/unlock_area
without holding the NAND device lock. On controllers that implement
SET_FEATURES via multiple low-level PIO commands, these can race with
concurrent UBI/UBIFS background erase/write operations that hold the
device lock, resulting in cmd_pending conflicts on the NAND controller.

Add nand_get_device()/nand_release_device() around the lock/unlock
operations to serialize them against all other NAND controller access.
