  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: usbusx2y: validate URB actual_length in interrupt callback\n\ni_usx2y_in04_int() processes the interrupt URB data without checking\nurb-\u003eactual_length.  A short transfer from a malfunctioning device\nwould cause the handler to process uninitialized heap data from the\nkmalloc-allocated in04_buf, which is then copied to the mmap-accessible\nctl_snapshot[] array.\n\nFix by using kzalloc() for in04_buf to zero-initialize the buffer,\nand adding an actual_length check to skip processing on short\ntransfers while still resubmitting the URB.",
