NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek-debug-modules-wireless package and not the kernel-uek-debug-modules-wireless 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:

iommufd: Don't overflow during division for dirty tracking

If pgshift is 63 then BITS_PER_TYPE(*bitmap->bitmap) * pgsize will overflow to 0 and this triggers divide by 0.

In this case the index should just be 0, so reorganize things to divide by shift and avoid hitting any overflows.
