Summary
comedi: das6402: Fix bit shift out of bounds
Details

In the Linux kernel, the following vulnerability has been resolved:

comedi: das6402: Fix bit shift out of bounds

When checking for a supported IRQ number, the following test is used:

/* IRQs 2,3,5,6,7, 10,11,15 are valid for "enhanced" mode */
if ((1 << it->options[1]) & 0x8cec) {

However, it->options[i] is an unchecked int value from userspace, so the shift amount could be negative or out of bounds. Fix the test by requiring it->options[1] to be within bounds before proceeding with the original test. Valid it->options[1] values that select the IRQ will be in the range [1,15]. The value 0 explicitly disables the use of interrupts.
