  3. CVE-2024-49931
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

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: ath12k: arreglo de acceso fuera de los límites a la matriz en las estadísticas de SoC Actualmente, la matriz ath12k_soc_dp_stats::hal_reo_error está definida con un tamaño máximo de DP_REO_DST_RING_MAX. Sin embargo, la función ath12k_dp_rx_process() accede a ath12k_soc_dp_stats::hal_reo_error utilizando el ID de anillo SRNG de destino REO, lo cual es incorrecto. El ID de anillo SRNG difiere del ID de anillo normal, y este uso conduce a un acceso a la matriz fuera de los límites. Para solucionar este problema, modifique ath12k_dp_rx_process() para utilizar el ID de anillo normal directamente en lugar del ID de anillo SRNG para evitar el acceso a la matriz fuera de los límites. Probado en: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
