## Overview

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

drm/amdgpu: Fix memory leak in hpd_rx_irq_create_workqueue()

If construction of the array of work queues to handle hpd_rx_irq offload
work fails, we need to unwind. Destroy all the created workqueues and
the allocated memory for the hpd_rx_irq_offload_work_queue struct array.

## Affected

- `Linux >= e980e1d978e0eb4c0399cff37f175779237db53b < 3ba3814c00a4817eb1cd31eff08d921c40e5f3a4`
- `Linux >= 8e794421bc981586d0af4e959ec76d668c793a55 < 8b8da09da2701330e7f2c371655887e3d7defe90`
- `Linux >= 8e794421bc981586d0af4e959ec76d668c793a55 < 600de40ed50c8b5ecb9c7a4f41eb882066c15a00`
- `Linux >= 8e794421bc981586d0af4e959ec76d668c793a55 < 7136f956c73c4ba50bfeb61653dfd6a9669ea915`
- `Linux >= 5.15.58 < 5.15.75`
- `Linux 5.16`
