CVE-2019-14895: Buffer Overflow

Published Nov 21, 2019
·
Updated

A heap-based buffer overflow was discovered in the Linux kernel, all versions 3.x.x and 4.x.x before 4.18.0, in Marvell WiFi chip driver. The flaw could occur when the station attempts a connection negotiation during the handling of the remote devices country settings. This could allow the remote device to cause a denial of service (system crash) or possibly execute arbitrary code.

A vulnerability was found in marvell wifi chip driver in Linux kernel. There is a heap-based buffer overflow while attempting a connection negotiation during the handling of the remote devices country settings ( When STA connects to AP, mwifiexprocesscountryie function will be called for STA ). This could allow the remote device to cause a denial of service(system crash) or possibly execute arbitrary code.

— Red Hat

Linux Kernel is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the mwifiexprocesscountryie function in drivers/net/wireless/marvell/mwifiex/staioctl.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.
