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 ...

CVE-2023-54116: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: drm/fbdev-generic: prohibit potential out-of-bounds access The fbdev test of IGT may write after EOF, which lead to out-of-bound access for drm drivers with fbdev-generic. For example, run fbdev test on a x86+ast2400 platform, wi...

Vulnerability of functions drm_fbdev_dma_helper_fb_dirty(), drm_fbdev DMA_driver_fbdev_probe_tail(), and drm_fbdev DMA_driver_fbdev_probe() (drivers/gpu/drm/drm_fbdev_dma.c) in the Linux kernel, allowing a hacker to cause a service failure

The vulnerabilities of the functions drmfbdevdmahelperfbdirty, drmfbdev DMAdriverfbdevprobetail, and drmfbdev DMAdriverfbdevprobe drivers/gpu/drm/drmfbdevdma.c in the Linux kernel are related to the use of a null pointer dereferencing. Exploitation of these vulnerabilities could allow an attacker...

CVE-2024-58091: NULL Pointer Dereference

In the Linux kernel, the following vulnerability has been resolved: drm/fbdev-dma: Add shadow buffering for deferred I/O DMA areas are not necessarily backed by struct page, so we cannot rely on it for deferred I/O. Allocate a shadow buffer for drivers that require deferred I/O and use it as...

CVE-2024-50037

CVE-2024-50037 affects the Linux kernel’s DRM framebuffer path (drm/fbdev-dma). The root cause was that drm_fbdev_dma_fb_destroy() unconditionally invoked fb_deferred_io_cleanup() even when struct fb_info.fbdefio was NULL, leading to a warning trace in an Apple Silicon display driver context. The...
