"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nusb: gadget: aspeed_udc: check endpoint DMA allocation\n\nast_udc_probe() allocates a coherent DMA buffer used as the backing store\nfor endpoint buffers. ast_udc_init_ep() derives per-endpoint buffer\npointers from udc->ep0_buf, so a failed allocation is dereferenced during\nprobe.\n\nCheck the allocation before endpoint setup. The existing probe error path\ncalled ast_udc_remove(), which unregisters the gadget unconditionally and\nis not safe before usb_add_gadget_udc() succeeds. Add a local cleanup\nhelper for probe failures so pre-registration failures only unwind the\nresources that were actually initialized.\n\nThis was found by a local static analysis checker for unchecked allocator\nreturns while scanning Linux 6.16. The change was checked by applying it\nto current mainline and by running checkpatch. I do not have access to\nAspeed UDC hardware, so no runtime testing was performed."
