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
