In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
wifi: mac80211: mesh: reset the CSA state when leaving<\/p>\n
ifmsh->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.<\/p>\n
Additionally, 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.<\/p>\n
Refactor the reset and call it in ieee80211_stop_mesh() to fix it all.<\/p>\n","protected":false},"excerpt":{"rendered":"
