CVE-2023-54116

CVE-2023-54116 targets the Linux kernel’s DRM fbdev path (drm_fb_helper_memory_range_to_clip) where fbdev tests may write past EOF, causing out-of-bounds accesses and kernel hangs. The root cause is unsafe damage-rectangle computation: buffers are page-size aligned and the DIV_ROUND_UP usage can ...
