CVE-2022-47522 is a high-severity flaw (CVSS 7.5) affecting ieee 802.11, tz670 firmware, tz570 firmware. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
The IEEE 802.11 specifications through 802.11ax allow physically proximate attackers to intercept (possibly cleartext) target-destined frames by spoofing a target's MAC address, sending Power Save frames to the access point, and then sending other frames to the access point (such as authentication frames or re-association frames) to remove the target's original security context. This behavior occurs because the specifications do not require an ac
