Description

wifi: iwlwifi: mvm: avoid NULL pointer dereference

In the Linux kernel, the following vulnerability has been resolved:

wifi: iwlwifi: mvm: avoid NULL pointer dereference

iwl_mvm_tx_skb_sta() and iwl_mvm_tx_mpdu() verify that the mvmvsta

pointer is not NULL.

It retrieves this pointer using iwl_mvm_sta_from_mac80211, which is

dereferencing the ieee80211_sta pointer.

If sta is NULL, iwl_mvm_sta_from_mac80211 will dereference a NULL

pointer.

Fix this by checking the sta pointer before retrieving the mvmsta

from it. If sta is not NULL, then mvmsta isn't either.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity none, availability high.
