## Overview

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

wifi: ath11k: fix array out-of-bound access in SoC stats

Currently, the ath11k_soc_dp_stats::hal_reo_error array is defined with a
maximum size of DP_REO_DST_RING_MAX. However, the ath11k_dp_process_rx()
function access ath11k_soc_dp_stats::hal_reo_error using the REO
destination SRNG ring ID, which is incorrect. SRNG ring ID differ from
normal ring ID, and this usage leads to out-of-bounds array access. To fix
this issue, modify ath11k_dp_process_rx() to use the normal ring ID
directly instead of the SRNG ring ID to avoid out-of-bounds array access.

Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1

## Affected

- `linux_kernel < 5.10.227`
- `linux_kernel >= 5.11, < 5.15.168`
- `linux_kernel >= 5.16, < 6.1.113`
- `linux_kernel >= 6.2, < 6.6.55`
- `linux_kernel >= 6.7, < 6.10.14`
- `linux_kernel >= 6.11, < 6.11.3`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.11.3`
