CVE-2026-53068

CVE-2026-53068 (Linux kernel, drm/komeda AFBC size check) Root cause: integer overflow in the calculation of the minimum required framebuffer size (AFBC payload size + framebuffer offset) during validation, allowing a malformed, undersized drm_gem_object to slip through. Impact: potential out-of-...
