CVE-2025-38043

CVE-2025-38043 affects the Linux kernel firmware/arm_ffa path: a fix sets the dma_mask for FFA devices to prevent DMA allocation using a raw device pointer, which previously triggered a kernel warning “dma_alloc_attrs” in mapping.c. The vulnerability’s impact, per the description, is to avoid mis...
