| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to the wifi component of the Linux kernel, specifically with the brcmfmac driver. The problem occurs when the driver tries to dereference NULL pointers in the cfg80211 pmksa function. This happens because the wpa supplicant 2.11 sends SSID-based PMKSA deletion commands, which the brcmfmac driver is not prepared to handle. The PMKID V3 operations support SSID-based updates, so the SSID needs to be copied. The vulnerability can be exploited to cause a denial of service.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
