[PATCH 0/2][SRU][X] CVE-2019-3846/CVE-2019-10126: Marvell WiFi-Ex memory corruption

[Tyler Hicks]

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.

Both patches are straightforward backports. Build logs show no related compiler
warnings. I am unable to test the Marvell WiFi-Ex driver.
