Summary
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.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
