CVE-2026-93262
Description
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.
