CVE-2024-58091

In CVE-2024-58091, the Linux kernel DRM fbdev code (drm/fbdev-dma) was updated to add a shadow buffer for deferred I/O because DMA areas are not always backed by struct page. The root cause is that deferred I/O cannot reliably rely on struct page backing for those DMA areas, so the fix introduces...
