Vulnerability from github – Published: 2025-12-24 12:30 – Updated: 2025-12-24 12:30

Details

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

wifi: iwlwifi: fix iwl_mvm_max_amsdu_size() for MLO

For MLO, we cannot use vif->bss_conf.chandef.chan->band, since that will lead to a NULL-ptr dereference as bss_conf isn't used. However, in case of real MLO, we also need to take both LMACs into account if they exist, since the station might be active on both LMACs at the same time.
