CVE-2025-38529

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> comedi: aio_iiro_16: Fix bit shift out of bounds<br /> <br /> When checking for a supported IRQ number, the following test is used:<br /> <br /> if ((1 options[i]` is an unchecked `int` value from userspace, so<br /> the shift amount could be negative or out of bounds. Fix the test by<br /> requiring `it-&gt;options[1]` to be within bounds before proceeding with<br /> the original test. Valid `it-&gt;options[1]` values that select the IRQ<br /> will be in the range [1,15]. The value 0 explicitly disables the use of<br /> interrupts.
