SUSE CVE-2026-114501

Pillow is a Python imaging library. From 11.2.1 until 13.0.0, Arrow export assumes that an image's rows are tightly contiguous and exports from im-blocks0.ptr even when PILLOWALIGNMENT makes alignedlinesize include row padding or an aligned offset before the first row. The resulting Arrow buffer...
