FKIE_CVE-2026-43302

Vulnerability from fkie_nvd - Published: 2026-05-08 14:16 - Updated: 2026-06-17 10:49
Severity
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
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 CONFIG_DMA_API_DEBUG enabled, the kernel occasionally reports a segment size mismatch. This is because 'max_seg_size' is not set. The kernel defaults to 64K. setting 'max_seg_size' to the maximum will prevent 'debug_dma_map_sg()' from complaining about the over-mapping of the V3D segment length.
