mac80211: mesh: reset the CSA state when leaving","description":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mac80211: mesh: reset the CSA state when leaving\n\nifmsh->csa is allocated in ieee80211_mesh_csa_beacon() and only freed\nin ieee80211_mesh_finish_csa(), i.e. when the channel switch completes.\nLeaving the mesh while a switch is still pending therefore leaks it.\n\nAdditionally, ifmsh->csa_role and ifmsh->chsw_ttl have their state leak\nin this case, so things can get mixed up in addition to the memory\nleak.\n\nRefactor the reset and call it in ieee80211_stop_mesh() to fix it all.","state":0,"publishedAt":"2026-10-06T08:46:20.317+00:00","modifiedAt":"2026-10-19T09:17:37.676+00:00","affected":[{"ecosystem":"Vendor
