Doc Text:
A heap-based buffer overflow was discovered in the Linux kernel's 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.

Description Dhananjay Arunesh 2019-11-21 07:36:48 UTC
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, mwifiex_process_country_ie 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.
