CVE-2022-49983

The issue CVE-2022-49983 affects the Linux kernel udmabuf driver. If the udmabuf DMA mask is not set explicitly, userspace DMA-BUF access via the CPU can trigger a warning in dma_map_sg_attrs (kernel/dma/mapping.c) during dma-buf CPU access flows (as shown in the stack trace). The vulnerability i...
