CVE-2019-3846
Published: 3 June 2019
A flaw that allowed an attacker to corrupt memory and possibly escalate privileges was found in the mwifiex kernel module while connecting to a malicious wireless network.
From the Ubuntu Security Team
It was discovered that the Marvell Wireless LAN device driver in the Linux kernel did not properly validate the BSS descriptor. A local attacker could possibly use this to cause a denial of service (system crash) or possibly execute arbitrary code.
