Unspecified impact via oversized framebuffer stride
Published Sep 24, 2026 · Updated Sep 24, 2026
Improper stride validation in affected Linux kernels allows attackers to cause unspecified impact via oversized framebuffer geometry. In simpledrm_device_create, drm_format_info_min_pitch() returns a 64-bit pitch that was assigned to stride without rejecting values above INT_MAX. Reachability requires firmware or a bootloader to provide the simple framebuffer geometry; the upstream record does not state the resulting security consequence.
