JSON

An issue was discovered in the Linux kernel 5.8.9. The WEP, WPA, WPA2, and
WPA3 implementations reassemble fragments even though some of them were
sent in plaintext. This vulnerability can be abused to inject packets
and/or exfiltrate selected fragments when another device sends fragmented
frames and the WEP, CCMP, or GCMP data-confidentiality protocol is used.
