Jann Horn discovered that the OverlayFS and ShiftFS Drivers in the Linux kernel did not properly handle reference counting during memory mapping operations when used in conjunction with AUFS. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-15794) It was discovered that a buffer overflow existed in the 802.11 Wi-Fi configuration interface for the Linux kernel when handling beacon settings. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-16746) It was discovered that there was a memory leak in the Advanced Buffer Management functionality of the Netronome NFP4000/NFP6000 NIC Driver in the Linux kernel during certain error scenarios. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2019-19076)
