CVE-2026-93262

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

md/raid5-ppl: fix use-after-free in ppl_do_flush()

The loop in ppl_do_flush() continues iterating after calling
ppl_io_unit_finished(), touching io->pending_flushes and leading to a
use-after-free.

Add a break statement to stop the loop once io is freed.
