n the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: Fix invalid data access in ath12k_dp_rx_h_undecap_nwifi In certain cases, hardware might provide packets with a length greater than the maximum native Wi-Fi header length. This can lead to accessing and modifying fields in the header within the ath12k_dp_rx_h_undecap_nwifi function for DP_RX_DECAP_TYPE_NATIVE_WIFI decap type and potentially resulting in invalid data access and memory corruption. Add a sanity check before processing the SKB to prevent invalid data access in the undecap native Wi-Fi function for the DP_RX_DECAP_TYPE_NATIVE_WIFI decap type. Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: ath12k: Se ha corregido el acceso no válido a datos en ath12k_dp_rx_h_undecap_nwifi. En ciertos casos, el hardware podría proporcionar paquetes con una longitud superior a la longitud máxima del encabezado Wi-Fi nativo. Esto puede provocar el acceso y la modificación de campos del encabezado dentro de la función ath12k_dp_rx_h_undecap_nwifi para el tipo de decap DP_RX_DECAP_TYPE_NATIVE_WIFI, lo que podría provocar acceso no válido a datos y corrupción de memoria. Se ha añadido una comprobación de seguridad antes de procesar el SKB para evitar el acceso no válido a datos en la función Wi-Fi nativa undecap para el tipo de decap DP_RX_DECAP_TYPE_NATIVE_WIFI. Probado en: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1.
