CVE-2024-49931 Information

Description

In the Linux kernel the following vulnerability has been resolved:

wifi: ath12k: fix array out-of-bound access in SoC stats

Currently the ath12k_soc_dp_stats::hal_reo_error array is defined with a maximum size of DP_REO_DST_RING_MAX. However the ath12k_dp_rx_process() function access ath12k_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 ath12k_dp_rx_process() to use the normal ring ID directly instead of the SRNG ring ID to avoid out-of-bounds array access.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
