Sources and claim methodology

Upstream source description

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.
