omap_ssi_core: fix missing DMA mask setup for SSI controller device","description":"In the Linux kernel, the following vulnerability has been resolved:\n\nhsi: omap_ssi_core: fix missing DMA mask setup for SSI controller device\n\nThe OMAP SSI driver uses a synthetic HSI controller device allocated via\nhsi_alloc_controller(), which does not go through the normal OF/platform\ndevice initialization path.\n\nAs a result, the embedded struct device does not have a DMA mask\ninitialized by default.\n\nAfter recent DMA API hardening changes, dma_map_sg() and related helpers\nnow require a valid dma_mask to be present, otherwise the driver may\ncrash or trigger warnings when attempting DMA mapping operations.\n\nFix this by explicitly initializing the DMA mask for the SSI controller\ndevice and setting a 32-bit DMA mask, which matches the hardware\ncapabilities.","state":0,"publishedAt":"2026-09-11T19:44:57.291+00:00","modifiedAt":"2026-10-19T08:49:26.718+00:00","affected":[{"ecosystem":"Vendor
