Title
wifi: mt76: mt7996: fix null pointer deref in mt7996_conf_tx()
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7996: fix null pointer deref in mt7996_conf_tx()
If a link does not have an assigned channel yet, mt7996_vif_link returns
NULL. We still need to store the updated queue settings in that case, and
apply them later.
Move the location of the queue params to within struct mt7996_vif_link.
Severity
No CVSS data available.
