This set of vulnerabilities can allow local attackers in Wi-Fi range to inject traffic even in encrypted Wi-Fi networks, or get access to information of other users in the same Wi-Fi network.
If the system is not using Wi-Fi, it is not affected. These issues largely affect the Hardware / Firmware of Wi-Fi cards.
Two CVEs are also in the mac80211 stack of the Linux, and will be addressed by updates to the Linux Kernel. These issues have received CVE-2020-24586 and CVE-2020-24587. These and others CVEs are fixed in the various Wi-Fi firmware, which we will be releasing once they become available from the Wi-Fi card vendors support by Linux, via "kernel-firmware" updates.
