In the Linux kernel, the following vulnerability has been resolved: wifi: rsi: Fix memory corruption due to not set vif driver data size The struct ieee80211_vif contains trailing space for vif driver data, when struct ieee80211_vif is allocated, the total memory size that is allocated is sizeof(struct ieee80211_vif) + size of vif driver data. The size of vif driver data is set by each WiFi driver as needed. The RSI911x driver does not set vif driver data size, no trailing space for vif driver data is therefore allocated past struct ieee80211_vif . The RSI911x driver does however use the vif driver data to store its vif driver data structure "struct vif_priv". An access to vif->drv_priv leads to access out of struct ieee80211_vif bounds and corruption of some memory. In case of the failure observed locally, rsi_mac80211_add_interface() would write struct vif_priv *vif_info = (struct vif_priv *)vif->drv_priv; vif_info->vap_id = vap_idx. This write corrupts struct fq_tin member struct...
