Details

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.
