Description

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: remove station if connection prep fails If connection preparation fails for MLO connections, then the interface is completely reset to non-MLD. In this case, we must not keep the station since it's related to the link of the vif being removed. Delete an existing station. Any "new_sta" is already being removed, so that doesn't need changes. This fixes a use-after-free/double-free in debugfs if that's enabled, because a vif going from MLD (and to MLD, but that's not relevant here) recreates its entire debugfs.

Affected configurations

• linux linux kernel (>= 6.0 < 6.1.176) • linux linux kernel (>= 6.2 < 6.6.140) • linux linux kernel (>= 6.7 < 6.12.88) • linux linux kernel (>= 6.13 < 6.18.30) • linux linux kernel (>= 6.19 < 7.0.7) • linux linux kernel 7.1
