NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-6_4_0-150700_53_16-default package and not the kernel-livepatch-6_4_0-150700_53_16-default package as distributed by SLES. See How to fix? for SLES:15.7 relevant fixed versions and status.

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

comedi: aio_iiro_16: Fix bit shift out of bounds

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

if ((1 &lt;&lt; it-&gt;options[1]) &amp; 0xdcfc) {

However, it-&gt;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-&gt;options[1] to be within bounds before proceeding with the original test. Valid it-&gt;options[1] values that select the IRQ will be in the range [1,15]. The value 0 explicitly disables the use of interrupts.
