  "description": "In the Linux kernel, the following vulnerability has been resolved:  dmaengine: pxa: fix double counting of the hw descriptors  pxad_alloc_desc() was converted from          kzalloc(struct_size(sw_desc, hw_desc, nb_hw_desc), GFP_NOWAIT)  to kzalloc_flex(), which sets the __counted_by() counter sw_desc-\u003Enb_desc itself - but only where the compiler has __builtin_counted_by_ref(), so from gcc 15.1 or clang 22.1 on. The loop below it still increments nb_desc, which makes it come out doubled there and correct elsewhere.  nb_desc is what pxad_free_desc() iterates over and what set_updater_desc() indexes from, so set it explicitly and drop the increment. The error path has to lower it to the number of descriptors allocated so far, otherwise pxad_free_desc() would free entries that were never allocated.",
