  "description": "In the Linux kernel, the following vulnerability has been resolved:  comedi: Fix memory leak in compat_insnlist()  \u0060compat_insnlist()\u0060 handles the 32-bit version of the \u0060COMEDI_INSNLIST\u0060 ioctl (whenwhen \u0060CONFIG_COMPAT\u0060 is enabled).  It allocates memory to temporarily hold an array of \u0060struct comedi_insn\u0060 converted from the 32-bit version in user space.  This memory is only being freed if there is a fault while filling the array, otherwise it is leaked.  Add a call to \u0060kfree()\u0060 to fix the leak.",
