  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\nwifi: mac80211: remove station if connection prep fails\nIf connection preparation fails for MLO connections, then the\ninterface is completely reset to non-MLD. In this case, we must\nnot keep the station since it's related to the link of the vif\nbeing removed. Delete an existing station. Any \"new_sta\" is\nalready being removed, so that doesn't need changes.\nThis fixes a use-after-free/double-free in debugfs if that's\nenabled, because a vif going from MLD (and to MLD, but that's\nnot relevant here) recreates its entire debugfs.", "A flaw was found in the Linux kernel's mac80211 Wi-Fi subsystem. When Multi-Link Operation (MLO) connection preparation fails, the system may not correctly remove the associated station. This can lead to a use-after-free or double-free vulnerability in the debugfs component, potentially causing system instability or unexpected behavior." ],
