## Overview

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

drm/xe: Fix memory leak in xe_vm_madvise_ioctl

When check_bo_args_are_sane() validation fails, jump to the new
free_vmas cleanup label to properly free the allocated resources.
This ensures proper cleanup in this error path.

(cherry picked from commit 29bd06faf727a4b76663e4be0f7d770e2d2a7965)

## Affected

- `linux_kernel >= 6.18, < 6.18.20`
- `linux_kernel >= 6.19, < 6.19.10`
- `linux_kernel = 7.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.19.10`
