CVE-2019-14901: Buffer Overflow
First published: Mon Nov 18 2019(Updated: )
A flaw was found in the Linux kernel's Marvell wifi chip driver. A heap overflow in  mwifiex_process_tdls_action_frame function in marvell/mwifiex/tdls.c allows remote attackers to cause a denial of service(system crash) or execute arbitrary code. the station receive a tdls setup request or respone frame which the EID_SUPP_RATES IE 's length is larger than 32 will cause Heap Overflow.
