EUVD-2026-28572

In the Linux kernel, the following vulnerability has been resolved: drm/v3d: Set DMA segment size to avoid debug warnings When using V3D rendering with CONFIGDMAAPIDEBUG enabled, the kernel occasionally reports a segment size mismatch. This is because 'maxsegsize' is not set. The kernel defaults ...

CVE-2024-56594 drm/amdgpu: set the right AMDGPU sg segment limitation

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: set the right AMDGPU sg segment limitation The driver needs to set the correct maxsegmentsize; otherwise debugdmamapsg will complain about the over-mapping of the AMDGPU sg length as following: WARNING: CPU: 6 PID: 19...

CVE-2024-56594

CVE-2024-56594 references a Linux kernel vulnerability in the DRM/AMDGPU path where the sg segment length was not properly limited. The issue could cause over-mapping of AMDGPU sg length and trigger warnings from debug_dma_map_sg(), due to an incorrect max_segment_size. The connected advisories (...
