This problem is quite similar to the one fixed in commit\n920a9fa27e78 (\"net: asix: add proper error handling of usb read errors\").\n\nFor instance, usbnet_read_cmd() may read fewer than 'size' bytes,\neven if the caller expected the full amount, and aqc111_read_cmd()\nwill not check its result properly. As [1] shows, this may lead\nto MAC address in aqc111_bind() being only partly initialized,\ntriggering KMSAN warnings.\n\nFix the issue by verifying that the number of bytes read is\nas expected and not less.\n\n[1] Partial syzbot report:\nBUG: KMSAN: uninit-value in is_valid_ether_addr include/linux/etherdevice.h:208 [inline]\nBUG: KMSAN: uninit-value in usbnet_probe+0x2e57/0x4390
