In the Linux kernel, the following vulnerability has been resolved:comedi: das16m1: Fix bit shift out of boundsWhen checking for a supported IRQ number, the following test is used: /* only irqs 2, 3, 4, 5, 6, 7, 10, 11, 12, 14, and 15 are valid */ if ((1 << it->options[1]) & 0xdcfc) {However, `it->options[i]` is an unchecked `int` value from userspace, sothe shift amount could be negative or out of bounds. Fix the test byrequiring `it->options[1]` to be within bounds before proceeding withthe original test.
