Title
media: staging/intel-ipu3: Fix set_fmt error handling
Summary
In the Linux kernel, the following vulnerability has been resolved:
media: staging/intel-ipu3: Fix set_fmt error handling
If there in an error during a set_fmt, do not overwrite the previous
sizes with the invalid config.
Without this patch, v4l2-compliance ends up allocating 4GiB of RAM and
causing the following OOPs
[ 38.662975] ipu3-imgu 0000:00:05.0: swiotlb buffer is full (sz: 4096 bytes)
[ 38.662980] DMA: Out of SW-IOMMU space for 4096 bytes at device 0000:00:05.0
[ 38.663010] general protection fault: 0000 [#1] PREEMPT SMP

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.
