Descriptions
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
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: medios: staging/intel-ipu3: Corrija el manejo de errores set_fmt Si ocurre un error durante un set_fmt, no sobrescriba los tamaños anteriores con la configuración no válida. Sin este parche, el cumplimiento de v4l2 termina asignando 4 GiB de RAM y provocando los siguientes OOP [38.662975] ipu3-imgu 0000:00:05.0: el búfer swiotlb está lleno (sz: 4096 bytes) [38.662980] DMA: Fuera de SW-IOMMU espacio para 4096 bytes en el dispositivo 0000:00:05.0 [38.663010] falla de protección general: 0000 [#1] PREEMPT SMP
