- Summary
- wifi: mac80211: mesh: reset the CSA state when leaving
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: mesh: reset the CSA state when leaving
ifmsh->csa is allocated in ieee80211_mesh_csa_beacon() and only freed in ieee80211_mesh_finish_csa(), i.e. when the channel switch completes. Leaving the mesh while a switch is still pending therefore leaks it.
Additionally, ifmsh->csa_role and ifmsh->chsw_ttl have their state leak in this case, so things can get mixed up in addition to the memory leak.
Refactor the reset and call it in ieee80211_stop_mesh() to fix it all.
