Doc Text:	A stack-based buffer overflow was found in the Linux kernel's Marvell WiFi chip driver. An attacker is able to cause a denial of service (system crash) or, possibly execute arbitrary code, when a STA works in IBSS mode (allows connecting stations together without the use of an AP) and connects to another STA.

Description Dhananjay Arunesh 2019-11-21 07:57:25 UTC

A vulnerability was found in marvell wifi chip driver in Linux kernel. There is a stack-based buffer overflow in add_ie_rates function in drivers/net/wireless/marvell/libertas/cfg.c allows remote attackers to cause a denial of service(system crash) or possibly execute arbitrary code. When some STAs work in IBSS mode, they can connect to each other without AP. lbs_ibss_join_existing will be called  when STA joins IBSS network.
