In the Linux kernel, the following vulnerability has been resolved:
wifi: brcmfmac: cyw: pass PMKID to firmware if present
Zero out auth_status on initialization. Otherwise, garbage will
leak from the stack to the firmware (when ssid is less than 32 bytes
and/or when params->pmkid is set). Then, pass the params->pmkid to the
firmware (without it, the firmware caches a garbage PMKID on successful
authentication and denies a subsequent association request that includes
the PMKID).

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
