In the Linux kernel, the following vulnerability has been resolved:
comedi: Fix memory leak in compat_insnlist()
`compat_insnlist()` handles the 32-bit version of the `COMEDI_INSNLIST`
ioctl (whenwhen `CONFIG_COMPAT` is enabled). It allocates memory to
temporarily hold an array of `struct comedi_insn` 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 `kfree()` to fix the leak.
