## Overview

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

accel/amdxdna: Fix VMA access race

aie2_populate_range() and amdxdna_umap_release() access a saved VMA
pointer that may have already been freed, leading to a potential
use-after-free.

Remove the VMA accesses from these functions to avoid the race.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
