The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. An adversary can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP encryption key is periodically renewed.

A potential Time-of-Check to Time-of-Use (TOCTOU) vulnerability has been identified in certain HP PC products using AMI UEFI Firmware (system BIOS) which might allow arbitrary code execution, denial of service, and information disclosure. AMI has released updates to mitigate the potential vulnerability.

HP has identified a potential vulnerability in BIOS firmware of some Workstation products. Firmware updates are being released to mitigate these potential vulnerabilities.

A potential vulnerability in AMD System Management Mode (SMM) interrupt handler may allow an attacker with high privileges to access the SMM resulting in arbitrary code execution which could be used by malicious actors to bypass security mechanisms provided in the UEFI firmware.

Potential vulnerabilities have been identified in UEFI firmware (BIOS) for some PC products which may allow escalation of privilege and arbitrary code execution.

An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The WEP, WPA, WPA2, and WPA3 implementations accept plaintext frames in a protected Wi-Fi network. An adversary can abuse this to inject arbitrary data frames independent of the network configuration.

An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other clients even though the sender has not yet successfully authenticated to the AP. This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier to exploit other vulnerabilities in connected clients.
