Description

Mitigation: This flaw requires a system with marvell wifi network card to be attempting to connect to a attacker controlled wifi network. A temporary mitigation may be to only connect to known-good networks via wifi, or connect to a network via ethernet. Alternatively if wireless networking is not used the mwifiex kernel module can be blacklisted to prevent misuse of the vulnerable code. Statement: This flaw is currently rated as Important as it is possible for an attacker to setup a wifi access point with identical configuration in another location and intercept have the system auto connect and possibly be exploited.
