FreeBSD-kernel -- Multiple WiFi issues

Problem Description:
The paper “Fragment and Forge: Breaking Wi-Fi Through Frame
Aggregation and Fragmentation” reported a number of security
vulnerabilities in the 802.11 specification related to frame
aggregation and fragmentation.
Additionally, FreeBSD 12.x missed length validation of SSIDs and
Information Elements (IEs).
Impact:
As reported on the FragAttacks website, the “design flaws are hard
to abuse because doing so requires user interaction or is only
possible when using uncommon network settings.” Under suitable
conditions an attacker may be able to extract sensitive data or inject
data.
