A flaw that allowed an attacker to corrupt memory and possibly escalate
privileges was found in the mwifiex kernel module while connecting to a
malicious wireless network.

A flaw was found in the Linux kernel. A heap based buffer overflow in
mwifiex_uap_parse_tail_ies function in
drivers/net/wireless/marvell/mwifiex/ie.c might lead to memory
corruption and possibly other consequences.

One patch is a clean cherry pick and the other is a straightforward backport.
Build logs show no related compiler warnings. I am unable to test the Marvell
WiFi-Ex driver.
