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.

There are packages installed that are affected by a vulnerability referenced in the following CVE:
