In the Linux kernel, the following vulnerability has been resolved: drm/lima: call drm_mm_init() with a valid allocation range lima_vm_create() is currently run before va_start and va_end are set up, meaning they are both 0. lima_vm_create() runs drm_mm_init() with them as arguments for the allocator, and if DRM_DEBUG_MM is enabled the DRM_MM_BUG_ON check in drm_mm_init then fires, as seen here on exynos4412-odroid-u2: [ 1.736297] ------------[ cut here ]------------ [ 1.740370] kernel BUG at drivers/gpu/drm/drm_mm.c:931!
