wifi: brcmfmac: fix P2P action frame handling without device vif

Published Sep 17, 2026 CVSS n/a EPSS < 1% KEV · Not listed
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.
