      "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: ath12k: Fix peer lookup in ath12k_dp_mon_rx_deliver_msdu()\n\nIn ath12k_dp_mon_rx_deliver_msdu(), peer lookup fails because\nrxcb->peer_id is not updated with a valid value. This is expected\nin monitor mode, where RX frames bypass the regular RX\ndescriptor path that typically sets rxcb->peer_id.\nAs a result, the peer is NULL, and link_id and link_valid fields\nin the RX status are not populated. This leads to a WARN_ON in\nmac80211 when it receives data frame from an associated station\nwith invalid link_id.\n\nFix this potential issue by using ppduinfo->peer_id, which holds\nthe correct peer id for the received frame. This ensures that the\npeer is correctly found and the associated link metadata is updated\naccordingly.\n\nTested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.4.1-00199-QCAHKSWPL_SILICONZ-1"

      "value": "En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta:\n\nwifi: ath12k: Corrección de la búsqueda de par en ath12k_dp_mon_rx_deliver_msdu()\n\nEn ath12k_dp_mon_rx_deliver_msdu(), la búsqueda de par falla porque rxcb->peer_id no se actualiza con un valor válido. Esto es esperado en modo monitor, donde los *frames* RX omiten la ruta regular del descriptor RX que típicamente establece rxcb->peer_id. Como resultado, el par es NULL, y los campos link_id y link_valid en el estado RX no se rellenan. Esto provoca un WARN_ON en mac80211 cuando recibe un *data frame* de una estación asociada con un link_id inválido.\n\nSe corrige este potencial problema utilizando ppduinfo->peer_id, que contiene el ID de par correcto para el *frame* recibido. Esto asegura que el par se encuentre correctamente y que los metadatos de enlace asociados se actualicen en consecuencia.\n\nProbado en: QCN9274 hw2.0 PCI WLAN.WBE.1.4.1-00199-QCAHKSWPL_SILICONZ-1"
