MEDIUM 6.0EPSS 0.20%

Does this matter?

Lower severity and a low EPSS score (0.20%). Track it; it rarely justifies an emergency change on its own.

Description

Unnumbered Disconnect (U DISC) and malformed Aviation Very High Frequency Link Control frames can terminate sessions and lead to a loss of CPDLC functions requiring a reversion to voice communication and increased controller workload. This type of attack can be carried out remotely over radio frequency.
