Description
linux, linux-aws, linux-aws-5.0, linux-gcp, linux-gke-5.0, linux-hwe, linux-kvm, linux-oem-osp1, linux-oracle, linux-oracle-5.0, linux-raspi2 vulnerabilities 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)
