In the Linux kernel, the following vulnerability has been resolved:

hsi: omap_ssi_core: fix missing DMA mask setup for SSI controller device

The OMAP SSI driver uses a synthetic HSI controller device allocated via

hsi_alloc_controller(), which does not go through the normal OF/platform

device initialization path.

As a result, the embedded struct device does not have a DMA mask

initialized by default.

After recent DMA API hardening changes, dma_map_sg() and related helpers

now require a valid dma_mask to be present, otherwise the driver may

crash or trigger warnings when attempting DMA mapping operations.

Fix this by explicitly initializing the DMA mask for the SSI controller

device and setting a 32-bit DMA mask, which matches the hardware

capabilities. (NVD)
