NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek64k-modules-core package and not the kernel-uek64k-modules-core package as distributed by Oracle. See How to fix? for Oracle:10 relevant fixed versions and status.

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

comedi: das16m1: Fix bit shift out of bounds

When 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 &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.
