CVE-2019-14897: Canonical Ubuntu Linux

Critical severity, CVSS 9.8. EPSS: 2.9% chance of exploitation in the next 30 days.

A stack-based buffer overflow was found in the Linux kernel, version kernel-2.6.32, in Marvell WiFi chip driver. An attacker is able to cause a denial of service (system crash) or, possibly execute arbitrary code, when a STA works in IBSS mode (allows connecting stations together without the use of an AP) and connects to another STA.
