CVE-2023-52857

Local service interruption via DRM arithmetic overflows

Published May 21, 2024 · Updated May 23, 2026

Integer overflow in the MediaTek DRM driver in affected Linux kernel revisions allows local users to interrupt system availability. mtk_drm_gem_dumb_create multiplies 32-bit pitch and height values before storing the result in a wider size field, while plane code mixes integer widths when calculating DMA offsets. Exploitation requires local access to a system using the MediaTek DRM path; wrapped calculations can produce undersized buffers or incorrect DMA addresses and interrupt service.
