A vulnerability was found in Linux Kernel, where the wifi 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.

Affects: fedora-all [bug 1960505]
