Descriptions

In the Linux kernel, the following vulnerability has been resolved:

wifi: brcmfmac: cfg80211: Handle SSID based pmksa deletion

wpa_supplicant 2.11 sends since 1efdba5fdc2c ("Handle PMKSA flush in the
driver for SAE/OWE offload cases") SSID based PMKSA del commands.
brcmfmac is not prepared and tries to dereference the NULL bssid and
pmkid pointers in cfg80211_pmksa. PMKID_V3 operations support SSID based
updates so copy the SSID.
