Does this matter?

Lower severity and a low EPSS score (0.46%). Track it; it rarely justifies an emergency change on its own.

Description

A partial authentication bypass vulnerability exists on Atheros AR9132 3.60(AMX.8), AR9283 1.85, and AR9285 1.0.0.12NA devices. The vulnerability allows sending an unencrypted data frame to a WPA2-protected WLAN router where the packet is routed through the network. If successful, a response is sent back as an encrypted frame, which would allow an attacker to discern information or potentially modify data.
