CVE-2024-41094

The CVE-2024-41094 issue affects the Linux kernel DRM fbdev-dma path. The root cause is unsafe handling of memory for the framebuffer when smem_start is exported via module options, which can break on systems where DMA memory is backed by vmalloc and may trigger non-linear virt_to_phys address ch...
