  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: ath12k: fix inconsistent arvif state in vdev_create error paths\n\nath12k_mac_vdev_create() has three error path issues that leave arvif\nin an inconsistent state:\n\n1. When ath12k_wmi_vdev_create() fails, the function returns directly\n   without clearing arvif-\u003ear, which was already set before the WMI\n   call. Subsequent code checking arvif-\u003ear to determine vdev readiness\n   will see a non-NULL value despite no vdev existing in firmware.\n\n2. When ath12k_wmi_send_peer_delete_cmd() fails in err_peer_del, the\n   code jumped to err: skipping the DP peer cleanup and vdev rollback,\n   leaving num_created_vdevs, vdev maps and arvif list membership live.\n\n3. When ath12k_wait_for_peer_delete_done() fails, the code jumped to\n   err_vdev_del: skipping the DP peer cleanup.\n\nFix by changing the ath12k_wmi_vdev_create() failure to goto err instead\nof returning directly, routing both err_peer_del failure paths through\nerr_dp_peer_del: for proper DP peer and vdev rollback, and consolidating\nthe arvif state cleanup at err:.\n\nTested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.1.c5-00302-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.115823.3",
