In the Linux kernel, the following vulnerability has been resolved:
wifi: brcmfmac: fix P2P action frame handling without device vif
Some P2P action frame paths assume the P2P device vif is always
available. That is not true when userspace sends non-P2P public action
frames through the primary interface, or when action-frame abort runs
after the P2P device vif has not been created.
Fall back to the primary vif when aborting an action frame without a P2P
device vif, and guard P2P device saved IE access before using it for
peer channel search.
