## Overview

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

drm/tests: shmem: Hold reservation lock around madvise

Acquire and release the GEM object's reservation lock around calls
to the object's madvide operation. The tests use
drm_gem_shmem_madvise_locked(), which led to errors such as show below.

[   58.339389] WARNING: CPU: 1 PID: 1352 at drivers/gpu/drm/drm_gem_shmem_helper.c:499 drm_gem_shmem_madvise_locked+0xde/0x140

Only export the new helper drm_gem_shmem_madvise() for Kunit tests.
This is not an interface for regular drivers.

## Affected

- `linux_kernel >= 6.16, < 6.18.16`
- `linux_kernel >= 6.19, < 6.19.6`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.19.6`
