CVE-2025-40131

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> wifi: ath12k: Fix peer lookup in ath12k_dp_mon_rx_deliver_msdu()<br /> <br /> In ath12k_dp_mon_rx_deliver_msdu(), peer lookup fails because<br /> rxcb-&gt;peer_id is not updated with a valid value. This is expected<br /> in monitor mode, where RX frames bypass the regular RX<br /> descriptor path that typically sets rxcb-&gt;peer_id.<br /> As a result, the peer is NULL, and link_id and link_valid fields<br /> in the RX status are not populated. This leads to a WARN_ON in<br /> mac80211 when it receives data frame from an associated station<br /> with invalid link_id.<br /> <br /> Fix this potential issue by using ppduinfo-&gt;peer_id, which holds<br /> the correct peer id for the received frame. This ensures that the<br /> peer is correctly found and the associated link metadata is updated<br /> accordingly.<br /> <br /> Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.4.1-00199-QCAHKSWPL_SILICONZ-1
