kernel: Reassembling fragments encrypted under different keys

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.

Incomplete cleanup in some Intel(R) PROSet/Wireless WiFi and Killer (TM) drivers before version 22.0 may allow a privileged user to potentially enable information disclosure and denial of service<b>&nbsp;</b>via adjacent access.
