Description

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).
