You're going to want to update your Wi-Fi and Bluetooth drivers today
If you haven't updated your wireless connectivity drivers in a while, now would be a good time to do so. Intel has published a long list of vulnerabilities in its Wireless Wi-Fi, Wireless Bluetooth, and Killer network adapters, and while they're likely nothing to panic about, they absolutely should be patched with the latest drivers as soon as possible.
When it comes to Wi-Fi vulnerabilities, Intel has published 23 CVE IDs across two advisories, Intel-SA-00539 and Intel-SA-00582. These affect heaps of Intel Wireless, AMT Wireless, and Killer Wi-Fi products. That includes popular Wi-Fi 6E and Wi-Fi 6 adapters found inside many gaming PCs, as the latest Z690 motherboards (and older motherboards back to Comet Lake) will include these parts alongside integrated Wi-Fi 6E or Wi-Fi 6 capabilities embedded in the chipset.
So if you see Intel Wi-Fi AX210, AX201, AX200; or Killer AX1675 and AX1650, in your device manager, you should update your drivers.
That's also true for some AMD CPU owners, as some AMD motherboards use Intel Killer Wi-Fi network adapters, such as the MSI MEG X570 Godlike.
The most severe vulnerabilities of the lot are rated at 7.1 CVSS, and there are three of that severity disclosed. All three relate to improper input validation either in the OS or software for various Wi-Fi cards, and may allow an unauthenticated user to enable either denial of service, information disclosure, or escalation of privileges «via adjacent access.»
That last bit is key, as it means an attacker needs to be on the same local network; share a Bluetooth connection; or share some other more localised network, such as a shared VPN, to carry out their nefarious plan.
