CVE-2019-14895: Buffer Overflow

First published: Thu Nov 21 2019(Updated: )

Linux Kernel is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the mwifiex_process_country_ie function in drivers/net/wireless/marvell/mwifiex/sta_ioctl.c. By sending a specially-crafted beacon packet, a remote attacker could overflow a buffer and execute arbitrary code or cause a denial of service on the system.
